I'm trying to recompile the USB microcontroller firmware starting from the drs_eval.c file but I'm not able to get a .iic file close to the one provided with the eval board. It seems to me that this drs_eval.iic file does not match the drs_eval.c and drs_eval.hex files or that I'm doing something wrong. Could you please help or give me an explanation.
I did not touch the firmware since a couple of years, but I can confirm that the drs_eval.iic is the correct firmware file, since we use this one on all of our boards. To program it, you need the Cypress USB Console. You remove the jumper (to detach the EEPROM), then power the board (which then boots from the internal memory), connect to the board via the Cypress console, the put back the jumper while the board is running, then program the file into the EEPROM.
Thank you Stefan.
Would that be possible to get the corresponding drs_eval.c source file since I'm assuming the one provided with the eval board is not the right one?
There is only one drs_eval.c version around, and I confirm that it is the one in the distribution. If you use different compiler settings, like optimisations, you might get a different executable file (and thus a .iic file), but the files have the same functionality.
