Up until now, docs said that RAM boot happens, when foboot finds `0x17ab0f23` in first 56 bytes of loaded binary. That wasn't the case, it was checking only first 12 bytes. `for` loop did at most `(max_check/4)-1` iterations, which is equal to 15, because `max_check` has the value of `rx_buffer` size from usb-dev.c. 15 times 4 byte words results in 60 checked bytes, but there was also division by 4 when accessing items of `dfu_buffer`, which reduced number of checks to 3. I also corrected the docs from 56 checked bytes to 60. |
