External Memory Error when flashing Nucleo-575ZI-Q + GFX02Z1 via TouchGFX or CubeIDE

[Neyus]

Hello,

this error really drives me crazy. When trying to flash the programm from the ToughGFX App or CubeIDE the external Memory can't be erased. I use the recommended CubeMXVersion of 6.14 and have the latest CubeProgrammer and CubeIDE with STM32Cube FW_U5 V1.7.0. The whole ToughGFX log is attached. Thanks in advance!

These are the following errors that are occurring:

TouchGFX:

Erasing memory corresponding to sector 0:

CubeIDE:

Hello @Neyus ,

Were you able to flash before ? If yes have you tried to manually erase memory with STM32CubeProgrammer ?

Hello @LouisB 

I tried erasing the external memory with the CubeProgrammer without success. Flashing the internal Flash works, but it fails every time I try to flash the external one. Could the Display Board be Faulty? I also tried downgrading the IDE and Programmer but nothing works.

Hello @Neyus ,

What's the message you get when you can erase / flash in cube programmer ?

Hello @LouisB ,

I have now imported the .stdl file that TouchGFX has provided for the exact board + external screen combination. When trying to do a mass erase, this error occours:

There is no write protection enabled for the adress of the flash chip in CubeProgrammer

I am also not able to connect the board to ST-Link Utility and updated the board with CubeIDE to the newest ST-Link Firmwareversion

Hello @Neyus,

Did you try to disable read protection option byte ?

Hello @LouisB,

yes, the read's out protection option was set to AA. The error still persists.

Hello @Neyus ,

In cube programmer did you select the right external loader ? If not the one from your board is not bundle with Cube MX, but is available in your TGFX project.

1. Search for a .stldr file in your TGFX project ( go in the gcc folder) and copy it in C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\ExternalLoader .

2. Restart your CubeMx software

3. Go in the external loader tab and search for u575 gfx and select the one you just added

4. Now you can try a full chip erase on the external memory

BR,

Hello @LouisB,

Yes, I have already imported the external loader from the GCC folder for this specific board combination into the CubeProgrammer, but I'm still unable to read from or flash the external chip.

Is it possible that you send me your project ?
