External Loader for STM32G0B0CET6

[cb.7]

We have developed an application with LCD display in which we use TouchGFX and external SPI flash memory, the microcontroller used is STM32G0B0CET6.

I wrote an external loader for STM32G070RBT6 (tested and worked) and simply rewrote it for STM32G0B0CET6, but it doesn't work on the latter.

It always gives me an error verifying at the same address.

The suspicion is that there is a bug related to the STM32G0B0xx family (id 0x467).

Has anyone had the same problem?

I have same problem.

I developed an UI with NUCLEO eval STM32G0B1RE and I used MX25L6433F_NUCLEO-G0B1RE.stldr. 

But it is not working for STM32G0B0KET6.

Hi ,,

I have some good experience regarding generating EX-Loader .

I successfully wrote codes for my different H7 boards with winbond qspi of different capacities.

Share the interfaced i/os details b/w stm <> qspi. I will try to do for you.

here is my latest TouchGFX Board with STM32H745 & 2.95" , 854X480 TFT.

The PCB has 4 layers .

The board has Modbus RTU Master over same usb cable and I can simulate values on TFT.

the custom ex-loader is done by me for W25Q256JV,,,

below is the SOM i used with above tiny TouchGFX experiment.

regards

I had constructed this   https://github.com/cturvey/stm32extldr/tree/main/g0_mx25l6433f

The underlying mechanics could be retargeted for assorted Macronix (MX25), Winbond (W25) and ISSI / Infineon QSPI chips.
