Hi guys
I’m having trouble using the daisy bootloader and BOOT_SRAM.
The program is not loading.
I know that the bootloader is working correctly because when i use BOOT_QSPI instead it loads my program fine (apart from performance issues, hence my wish to use BOOT_SRAM).
There is no SoS led pattern.
I have no idea how to debug this really, here is my build output, it looks exactly like i would expect it to which memory not taken up in flash or QSPI and instead in DTCMRAM. Also it doesnt look too big
