Can anyone explain this for a new user of a BL5S220 SBC.
To check my new board, I ran a simple routine to pulse the STAT pin. All OK when run in ram. Compiled to flash, disconnected programmer and reboot. Still OK.Booted from flash.
Then loaded a slightly more advanced program - sent a "hello world" to a serial lcd on RS232 port F. Once again, all OK when run in ram, but failed to run when complied to flash, with program cable disconnected, then reboot. (Note: works when run from flash when cable still attached, just won't work from a reboot. ??)
