X-NUCLEO_LIV4A1 not working after fw update.

[leo_]

Hello.

 

After updating x-nucleo-liv4a1 using the GNSS FW Upgrader program, it no longer works.

 

Afterwards, I tried to update using Teseo Firmware Upgrade, but an error occurred.

How can I revert a module?

Thank you.

Hi Leo,

To upgrade firmware for X-NUCLEO-LIV4A1, can you use a USB to UART cable and connect to the UART-TX and UART-RX pins directly? The firmware upgrade tool in the X-CUBE- firmware directory is only tested for LIV3 and VIC3 modules.

Hardware modifications are these:

• Remove jumpers J8 and J11.
• Connect RXD of UART to USB cable to J11-pin-2
• Connect TXD to UART to USB cable to J8-pin-2.

In Teseo Suite, can you try checking the flags Erase and Recovery?

After you press START on the Teseo Suite, please press and release the reset button on LIV4F.

Please try this and let me know.

Thanks,

George
