Here is an updated version of the pico-cram README.
I am still not sure that I am doing this right.
Pico-Ice Cram Configuration
There are two ways to program the FPGA. A bitstream can be witten to
FLASH and loaded by the FPGA when booting, or the bitstream can be
directly written to the fpga's configuration RAM (cram). This SDK
example shows how to directly write the bitstream to the cram
To build the executable type
cmake .
This drives a multistage process. In the first stage, a python
program reads in the bitstream and writes out a .h file with the
bitstream data embedded in it.
python3 rgb_blink.py > rgb_blink.h
In the second stage, the new .h file is compiled into an executable
This is an RP2040 executable which can be run on the RP2040 and will
drive the cram initialization process for the FPGA.
Did I get that right?
So what do I do next?
Which file is that executable?
picoasm/picoasm ??
Do I set the baud rate, and then drag it into the USB folder?

Thank you, this is good to have this extended README, and I will integrate it in the next release, eventually modifying it in the process, but it looks accurate.
