v0.11.0-esp32-20220411

2022/04/11 Release, based on OpenOCD v0.11.0

Features:

• Synchronized with upstream.
• esp/ci: Added build for MacOS ARM64.
• esp-config: Added Espressif USB bridge board configs.
• esp/flash: Added octal flash support.
• esp/flash: Added MXIC 32MB flash chip support. Solves problem mention in #218.
• esp/freertos: Print FreeRTOS kernel version.
• esp/freertos: Read TCB_t offsets from ESP-IDF symbol table. This adds support for different TCB block layouts which can be caused by different FreeRTOS configurations.

• semihosting: Added 'arm semihosting_basedir' command. See description here

Bug fixes:

• xtensa: Call 'keep_alive during' register/memory restore to avoid gdb warning.
• esp32s3: Added automatic target reset upon GDB connection if memory protection is enabled (#190, #183, #176 (comment))
• esp/xtensa: Added support for proper Xtensa semihosting break instruction. According to Xtensa spec 'break 1,14' should be used for semihosting calls. This will be fixed in IDF soon too.
• target/esp: Fixed ESP32-S2 & S3 IROM region boundaries. It could lead to ROM debugging problems.

v0.11.0-esp32-20211220

2021/12/20 Release, based on OpenOCD v0.11.0

Features:

• Merge with upstream. Bump version to v0.11.0. This also closes a couple of issues: #198, #199, and #196
• esp/riscv: Add flash breakpoints support for Espresif RISCV chips. Currently, only ESP32-C3 is supported.
• jtag/esp_usb: Add Espressif USB bridge support

Bug fixes:

• esp/flash: Add check for a maximum number of flash mappings. Prevent flash driver crash when flasher stub returns garbage upon flash mappings request.
• esp32s3/esp_usb_jtag: Dummy jtag call before running an algorithm. It works around the problem on ESP32-S3 when USB JTAG device gets stuck after running flasher stub algorithm. That problem leads to a flash probing problem upon GDB connection or any other flash access command.
• jtag/esp_usb: Check if USB device handle is valid before close
• esp32s3: Add missed irom_mask_low mem region to the config.
• rtos: Fix heap usage after free during rtos_destroy
• esp_apptrace: Restart idle timeout after target reconnection. That could lead to data timeout error after target reset during tracing.

v0.10.0-esp32-20211111

2021/11/11 Release, based on OpenOCD v0.10.0

Features:

• flash/esp32s3: Added ESP32-S3 flash support (#178 (comment)). Access to chip's flash is supported including setting breakpoints there.
• esp/riscv: Added coverage data collection support for Espressif RISCV chips. Currently this functionality is verified for ESP32-C3 only.
• esp_usb_jtag: Added ability to filter out USB device by product serial. Now it is possible to specify which USB device should be used by command espusbjtag serial <serial_num>.

Bug fixes:

• esp32s2-c3: Added automatic target reset upon GDB connection if memory protection is enabled (#190, #183, #176 (comment)).
• esp32c3: Avoided missing chip reset due to problems with dmi_scan. This led to the problem when SW breakpoints and syscalls do not work.
• esp32c3: Enables ebreaks in 'FLASH_BOOT' mode only. This led to the problem with flashing esp32c3 over UART with connected OpenOCD.
• flash/esp: Added detection of unexpected target algorithm exit during a flash read/write. Now the error message is printed if flash stub invocation ended up accidentally.
• flash/esp: Fixed cache flush in flasher stub for esp32s2/esp32c3. This problem led to partial data writes to flash.
• esp_usb_jtag: Added USB device re-enumeration in case of data transfer problem (#176, #178). This problem led to built-in USB-JTAG getting stuck after HW reset.
• esp_usb_jtag: Made tx/rx routines a bit more responsive and reliable. Added several attempts to tx/rx data in of failure.
• esp32s2-s3: Added power config register reset to prevent getting stuck in soft reset. This problem led to application getting stuck after resetting the target with reset run.
• esp32c3: Fixed WDT reset issue while waiting for resume after soft reset. This problem led to application getting stuck after resetting the target with reset run.
• esp_remote: Fixed runtest function. This problem was causing error during ESP32-C3 examination.
• gdb_server: Fixed registers access error reporting. Now it is controlled by gdb_report_register_access_error command. This problem led to RISCV GDB register access reporting and when GDB register packet is received when target is running.
• algorithm: Fixed cleaning up algorithm data upon failure.
• algorithm: Fixed '.data' and '.bss' section size alignment to avoid possible data corruption when running algorithms.

v0.10.0-esp32-20210902

2021/09/02 Release, based on OpenOCD v0.10.0

Features:

• esp_remote: New command to set JTAG clock freqency

Bug fixes:

• esp_xtensa_smp: Fixes problem when APP CPU is left unexamined after target is reset externally by esptool.py (#160)
• esp_xtensa_smp: Fixes TRAX tracing start on one core only
• xtensa: Fixes memory leak in TRAX tracing dump command handler
• algorithm: Skip loading sections with zero size. This led to the algoritm run failure when algorithm image has zero-sized sections.

v0.10.0-esp32-20210721

2021/07/21 Release, based on OpenOCD v0.10.0

Features:

• esp32s3: Added base support for the latest ESP32-S3 chip revision. It includes base debugging support w/o flash support and other features.
• tcl/esp32s3: Added esp_get_mac support for ESP32-S3.
• esp32c3: Added separate target for ESP32-C3 chip. Now ESP32-C3 has its own target implemented basing on RISCV one. Thsi allows to keep ESP32-C3 specific features in separate module and minimize modification to base RISCV target.
• esp/apptrace/esp32c3: Added application level tracing support for ESP32-C3.
• algorithm/esp32c3: Added support for running algorithms on ESP32-C3.
• flash/esp32c3: Added flash support for ESP32-C3 (#165).
• riscv: Added command to mask IRQ during stepping. Implemented ARM-like command to control how IRQs are controlled during stepping. Currently to modes are supported: off and steponly.
• riscv: Implemented batch JTAG ops for memory read. Combined JTAG operations into batches to speed up memory reads.
• riscv: Emulated 8-/16-bit memory access via SBA using 32-bit read/write. SBA mode allows to access memory on running target. When 8-/16-bit memory accesses via SBA are not supported they are emulated via 32-bit ones if it is possible.
• loaders/esp: Added encrypted flash support for esp32, esp32s2 and esp32c3.
• loaders/esp: Added command to enable/disable CPU clock boosting when flasher stub is running on target. This allows to increase flash programing speed significantly.
• loaders/esp: Enable by default CPU clock boosting when programming via program_esp. Clock can be restored after flashing when restore_clock option is specified.
• loaders/esp: Added command esp verify_bank_hash to verify flash uploads using sha256 hash.
• esp: Added Espressif USB JTAG/serial debug unit and USB Bridge udev rules.
• esp: Added release binaries signing for MacOS.

Bug fixes:

• riscv: Disabled watchpoints on stepping to avoid watchpoint re-triggering.
• tcl/esp: Added check for flash support before running program_esp to provide clearer error reasoning for users (#165 (comment)).
• freertos: Made threads list updating tolerant to list reading errors.
• target/riscv: Added get_gdb_arch target API implementation to avoid GDB errors when riscv arch is not exactly specifed (#144 (comment)).
• esp32c3: Call rtos post_reset_cleanup method after reset to clear RTOS data (#144).
• riscv: Avoided increasing dmi_busy_delay due to garbage data received by dmi_scan during chip reset. Thsi allows to avoid unnecessary and abnormal increasin of dmi_busy_delay leading to quite slow JTAG communication after several target resets.
• esp/apptrace: Added target connection status check while polling for apptrace data (#149). This allows to avoid apptrace data losing due to target reset.
• target/{esp32s2,esp32s3,esp32c3}: Disabled SWD on reset or halt (#153).
• jtag_esp_remote: Added several fixes of the ESP Remote protocol JTAG driver.
• esp_usb_jtag: Fixed stack overflow. This prevents OpenOCD crashing or stucking in infinite loop when started w/o connected device.
• esp: Fixed files paths typo in boards description file.

v0.10.0-esp32-20210401

2020/04/01 Release, based on OpenOCD v0.10.0

v0.10.0-esp32-20210329

2021/03/29 Release, based on OpenOCD v0.10.0

Features

• flash/esp_xtensa: Added compression support for write operations. Compression can be enabled by adding compress argument to program_esp command. Compression is not enabled by default, yet.
• rtos/FreeRTOS: Changed task list update algorithm basing on uxTaskNumber. This reduces the amount of data transferred over JTAG in some cases, and makes stepping through the code faster.
• target/esp32c3: Added SoC reset support. reset halt command now resets the digital peripherals, in addition to the CPU, same as it does on esp32 and esp32s2.
• target/esp32c3: Reduced timeouts to reasonable values
• board/esp32c3-ftdi: set lower JTAG clock used by default. Since there is no development board with FT2232H and ESP32-C3 yet, they are most likely connected by jumper cables, so a lower frequency should be used.
• xtensa: Made 'xtensa_smpbreak_get' returning configured value

Bug fixes:

• esp32s3: Disabled flash support by default, since it's not implemented yet. It will be re-enabled once the feature is implemented.
• esp/semihost: Added callback to disable WDTs upon syscall.
• riscv: Maintain target halted state across reset
• riscv: Fixed RTOS checks in reset procedure
• riscv: Fixed semihosting code to adjust the PC to the next instruction also for GDB fileio
• esp/gcov: Ensured that esp gcov dump is run on examined target
• esp/gcov: Fixed acknowledgement of the block with command w/o response data
• esp/gcov: Halt target before on-the-fly gcov dump
• semihosting: Fixed file name length parameter for GDB File IO to match GDB docs.
• xtensa: Marked target as unexamined when 'powered' bit is reset during several polling periods.
• In this release we have stared running the test suite with sanitizers (AddressSanitizer, UndefinedBehaviorSanitizer) enabled, and fixed the following issues:
  • target/esp_xtensa_apptrace: Fixed 'unaligned buffer' issue
  • esp32s2: Fixed left shift runtime errors found by sanitizers
  • gdb_server: Fixed AdressSanitizer issue caused by missing null character
  • xtensa: Fixed sanitizer warnings when shifting integer constants
  • xtensa: Fixed buffer overflow due to incorrect size allocated for wide user registers
