unable to boot on esp32 wroom module board

[jirmjos]

Hi Jorgen,

Sorry to bother you, so much.

Flashed board (at this moment I´m only have wroom modules at hand) but now it falls to a looping reboot I think is because try to init psram that this ESP32 module don´t have.
I try to disable psram trough idf.py menuconfig - ESP32 audio buffer and i2s pin config --->, but seems no effect.

Seems a issue yet fixed on esp-idf v4.2, that is the idf version I use, but for some reason is not aplying on this project
See : espressif/esp-idf#6063

I don´t know how to fix it.

That´s the monitor output:

Hi Jose
No problem - I will see if I can get it running on a non PSRAM board later today.

Hi Again,

I get snapclient on ESP32 Wroom module running.

Easy enough fix it, because only needed disable external spi ram trough menuconfig:
Component config ---> ESP32-specific ---> Support for external, SPI-connected RAM

My fault because fast reading error I messed up, PSRAM with SPI RAM.
On default ESP32 Wroom modules you need disable PSRAM and SPI RAM support.

Now seems my module are up, and next step is tunning configuration to my cheap PCM1502 dac board and propper attach it to esp32 (I see some references to ma12070 and i2c bus (that it´s not propper for my dac board) and finally I think then I can last configure and test snapcast.

Hi Jose - Nice yes you need to setup you own custom board - or get one of the MA12070p based setup. /J

[jorgenkraghjakobsen]

The repo is very much work in progress. The MA120 that I am using is not released yet. /J

[jirmjos]

Hi Jorgen,

I´m in process to buy this MA12070P board https://www.audiophonics.fr/en/amplifier-boards/balanced-class-d-10-20-21-40-amplifier-module-ma12070-160w-4-ohm-p-14732.html.
I hope they build enough well the board and mantain the good MA12070p spechs chip and his performance.
In few days I hoppe have this Merus/Infineon board in my hands and too some purchased ESP32 Wroover boards to start real test with target final hardware.

Meanwhile I try to steep forward to test and understand your snapcast client to tunning but with the hardware I have now .

Regards
