07/01/2023, 10:53 PMIs there some kind of magic sequence that causes SPI flash to fail writing? Re-compiled with -O0 and now code is bigger than 0xF00, but it's flashed well - a

07/02/2023, 4:38 AMwas able to get caravel control of the I/Os working, this is the config i ended up with👍 1 - a

07/02/2023, 5:49 AMwrote a lil script for
projects for controlling user-project I/Os over UART thru the caravel. between the 9600 baud limitation and the 16ms latency of the FTDI it's not particularly effective, but its a decent starting pointtiny_user_project - a

07/03/2023, 5:40 AMNow I have my program big enough to cause constant verification errors - a
Alexander Shabarshin
07/03/2023, 5:40 AMIt looks like data driven error, not noise or random writing error - it's consistent - a

07/03/2023, 5:41 AMif it's failing then it's always failing in the same place - a

07/03/2023, 5:43 AMRe-compiling program with different optimization flag makes it failing in different place - a
Alexander Shabarshin
07/03/2023, 5:47 AMMoreover even if I take different board with different chip it's failing exactly in the same place as on 1st board (with the same failing hex file) - a

07/03/2023, 7:11 AMit's probably when hex sections are not having length that is multiple of 16 … actually it was caused by writing over page boundaries - a
Alexander Shabarshin
07/03/2023, 7:12 AMso caravel_hkflash.py needs to be updated to handle those hex-files too- 1

07/18/2023, 3:53 AMI got my chips around a week ago, but was able to begin testing only now. Currently I have some issues in my user project which I'm trying to overcome. Meanwhile I could confirm that Caravel is fully functional (flash reading, program execution, UART and user WB) at least in core voltage range 3.3-7V. GF180 seems to be very durable process!👍 1a- 2
