Is it possible to put in the boot mode by software after reset? We know that The device put in bootloader mode after bm pin set Low to reset the device. But we couldn't reach the hardware. That`s why we need to use the software. We delete all code of the flash and reset the device. The device didn't go to bootloader mode. Is there any way to put in boot mode by software?
Thanks in advance
The only way to enter download mode is by pulling the BM pin low during a reset sequence.
Any reset type - hardware, watchdog or software reset will work but, the BM pin must be pulled low.
The on-chip ADI kernel program is the first code executed after a reset by the ARM7 processor - it reads the BM pin and based on its level enters the downloader (BM=0) or, exits to user code (BM=1).
