I’m running STM32 CubeProgrammer, but I cannot connect successfully to the LoRa-E5 Dev Board (nor the LoRa-E5 mini) to reprogram it.
I’m running on Mac OS (Big Sur), and have the board in DFU mode (it sends a byte sequence every second to the serial port), but it errors out.
19:50:46:249 : Timeout error occured while waiting for acknowledgement.
19:50:46:250 : No response from target received
19:50:46:250 : byte 0x7F sent successfully to target
19:50:46:343 : Wait ends after 1 loop, dataready = 0, delay = 105
19:50:46:343 : Timeout error occured while waiting for acknowledgement.
19:50:46:343 : No response from target received
19:50:46:343 : Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again…
Is there a particular timing trick to this?
Also, I recognize that doing this will purge the existing firmware and AT command functionality. I am somewhat disappointed in this as there seems to be nothing really equivalent to replace it with if one was to want similar functionality in the future.
