I am trying to use the XM125 pulsed radar breakout board.
Initially, I managed to flash the Acconeer Exploration Tool binary to the board from the STM32CubeProgrammer tool.
Hoever, the Exploration Tool itself gave me a timeout on the serial connection (as others are reporting too in different discussions).
I then flashed the Exploration Tool binary again, from within the Exploration Tool itself. This also seemed successful. However, the tool still gave the timeout error.
However, ever since, I am unable to flash the module again.
Both from STM32CubeProgrammer and from the Explorer Tool, I get an error saying that it cannot connect to the board in boot mode. The error message from STM32CubeProgrammer is:
Error: Activating device: KO. Please, verify the boot mode configuration and check the serial port configuration. Reset your device then try again…
From the Explorer Tool the error message is:
synchronization failed for ‘COM13’, make sure device is in DFU mode
I am pretty sure I am pressing the button in the right way and order and that the USB driver is OK.
I have tried it also on different PCs with the same result.
I am stuck on what to try next.
Any suggestions would be welcome.
