FET430UIF downgrade #24

Closed xhpohanka closed 7 years ago

Hi, I have followed your instructions for downgrade (http://dlbeer.co.nz/mspdebug/tilib.html) and ended up with probably blank device that shows in Linux still with id 2047:0010 and /dev/ttyACM0 node.

tilib driver wont initialize anymore

#mspdebug tilib --allow-fw-update

MSP430_GetNumberOfUsbIfs
MSP430_GetNameOfUsbIf
Found FET: ttyACM0
MSP430_Initialize: ttyACM0
tilib: MSP430_Initialize: Interface Communication error (error = 35)
tilib: device initialization failed

Do you please have any recommendation how to 'debrick' the programmer? I have tried msp430flasher for windows but it also is not able to initialize the device.

Hi Jan,

Those instructions were given to me by TI, although that was quite a few firmware versions back.

If you open the device up, you may be able to get access to a BSL interface to write new firmware. Of course, you will need to grab an older firmware image from somewhere and an older device to program with. Email me (dlbeer@gmail.com) if you have any trouble with this.

Cheers, Daniel

I fixed it by reading V3 firmware from another FET430UIF and, thanks.
