In fact, I've set BACKUP_RECOVERY_MAX_SIZE_IN_FLASH = 0 directly by editing customize.ldr file (without using IDE)
I've already tried the failsafe recovery , but didn't work.
The procedure says:
Now, if the the image doesn't work BUT has a valid image header AND passes it''''s CRC check, then this procedure can't occur, the unit still won't boot, and the module will need to be RMA'd.
What's stange, that my module boot perfectly and start my application OK. But can't update a new firmware !
Do you know what means RMA'd ?
