Undetected notecard after upgrading to 4.1.1

Hi,

I upgraded a notecard 1.5 european to 4.1.1 using stm32programmer, however after upgrading I can no longer contact the notecard using I2C, nor does it show up as an USB device (neither ACM or USB, so not in programming mode). See output from programming below:

Update:

The download URL was wrong (the $ tripped me up), and I probably flashed a 404 HTML page to the notecard. Any way to recover it?

By the way, putting $ in the name is a bit of a nuisance since it complicates shell scripting.

Hi @gauteh,

The good news is the Notecard should be recoverable. It’s a bit of a tricky process though. If you can power up the Notecard with the boot pin pulled high, then STM32 Cube Programmer will be able to connect and upload the correct binary. The problem is the BOOT pin is not labelled/does not exist on some of our Notecarriers (so consider this process unsupported). Which Notecarrier are you using (and which version)? That will help us figure out the best path forward.

Thanks,
Rob

Hi Rob,

thanks for your reply. I am using the Notecarrier B, I have both the green and the black version. Doesn’t seem like it has access to the BOOT pin, but maybe I can try and get directly to the BOOT pin on the notecard socket.

Regards, Gaute

Yeah unfortunately the Notecarrier-B doesn’t expose the BOOT pin. I don’t suppose you have a Notecarrier-A (black PCB) laying around you could use? With the A you should be able to wire VIO to the unlabelled pin between RST and SCL and then connect over USB.

Rob

I will add one on my next purchase.
