Topper69 commented 1 year ago

Hi,

I have just received my BP v4 and i tryed to update the firmware. Following the guide, i try: 1) minicom HiZ>$ Are you sure? y BOOTLOADER then the board reboots and minicom reconnect with the pompt. "HiZ>" like nothing happen.

2) By shorting PGC & PGD before connecting the boad: it have the same prompt has usual, so defenitly not in bootloader mode.

3) Both method (by tiping "$" then Y with the short on PGC&PCD), same problem.

Try on linux (rasp4) and win10, same issue impossible to get the boad in the bootloader mode. Of course the pirate-loader fails. udo ./pirate-loader_lnx --dev=/dev/ttyACM0 --hello +++++++++++++++++++++++++++++++++++++++++++ Pirate-Loader for BP with Bootloader v4+
Loader version: 1.0.2 OS: Linux +++++++++++++++++++++++++++++++++++++++++++

Opening serial device /dev/ttyACM0...OK Configuring serial port settings...OK Sending Hello to the Bootloader...ERROR No reply from the bootloader, or invalid reply received: 0 Please make sure that PGND and PGC are connected, replug the device and try again

I know that $ was not working properly on some old firmware. But shorting PGND and PGC while booting should always go into bootloader mode.

Maybe you need to update the bootloader also !!

I have already tried shorting PGD & PGC and no success. My buspirate stay in "normal" mode. But i'll try between GND and PGC

For now it's run in v7.0 firwmare, so the bootloader is not too old. With this firwmare JTAG is not working with openocd.

For JTAG I have made a fix on my merged branch https://github.com/psolyca/Bus_Pirate/commits/merged I have a build but did not published it... 😭

Could you share a .hex file for v4 board please? It'll be very helpful !!

Many thanks.

Just in case this jogs anyone's community spirit, I have this same issue and would certainly appreciate wisdom from anyone who has managed to update a fairly recently purchased bpv4. I am thinking that a pickit is going to be needed.

Hi, After unsuccessful tries with the USB bootloader mode, i bought a pickit to successfully flash it with the MPLAB IDE & ICSP header.
