GFX01M2_HelloWorld application on X-Nucleo-GFX01M2 w/ STM32G071 Nucleo. IAR makes, I can build, but attempts to download/debug do not work. Basic G071 demos work.

Well it's going to need a loader configured for it to push the QSPI content.

Really not sure how well that's supported on NUCLEO-64 platform, at least in a memory-mapped, execute-in-place sense.

The QPSI is better / appropriately wired on the NUCLEO-144 board

[PFabi.1]

It was my understanding that the GFX01M2 came preloaded with some images. A .hex file is generated and there is a batch file that I 'think' can use the STM32CubeProgrammer to upload those.

BUT - If I squint it appears the culprit is related to these two lines (see below) in the debug log related to the unknown ELF/DWARF Error Thoughts on that?

[Tesla DeLorean]

I'm #TeamKEIL so can't really help you with idiosyncrasies with IAR tools

These are presumably objects that IAR itself generated?

The memory might have existing content, but your build is generating other content, I'm not sure how similar / identical they are.

The X-NUCLEO-GFX01M2 uses SPI, and a mishmash of routing options, if I'm not mistaken.

Can STM32 Cube Programmer deal with this .ELF or .HEX ?

The X-NUCLEO-GFX02Z1 uses QSPI and maps to 0x90000000, not sure if the G071 facilitates that or not, or if the 0x90000000 on the linker side is just a convenient method of constructing content, and not actually addressable in that space, but rather fetched at a byte stream / blob level.

[PFabi.1]

Everything I am trying is "supposed" to work out of the box. At least this is how it is advertised by ST. I have downloaded the cube package for the GFX01M2 and the IAR workspace. It does include an extra process where they create the .hex file too. I will see if I can get things working using the cube programmer.

The G071 Nucleo board is one of about 5 demo application included with the cube package, so it certainly appears they are saying it works with the GFX01M2. It is also listed on the website as compatible.

Thanks for the help. I'll respond back if I figure something out.

BTW - I also tried the Keil workspace, and that one too had it's out-of-box issues. If I continue to fail using IAR I will try the Keil again and let you know the failure points on that one!

Keil is just as unfriendly as IAR -

Hi All,

The X-CUBE-DISPLAY software expansion pack is providing external loaders only for the STM32CubePpogrammer tool. And only for the listed Projects of NUCLEO + X-NUCLEO-GFX combinations inside the pack.

Sorry, but we're not providing external loaders for IAR and Keil.

However, it is still possible to debug also with these IDEs if you follow below steps:

1. Compile with your IDE (IAR / Keil / STM32CubeIDE)
2. Copy your generated .hex file into the folder Binary/.
3. Execute the programming script batch file in the same folder Binary
4. Attach your debugger or start it without downloading the program file

• For IAR, just press the button with the white circle and the green play icon which is also named Debug without Downloading
• For Keil, you can refer to https://developer.arm.com/documentation/ka003020/latest

Next release X-CUBE-DISPLAY.3.0.0 will contain source code and Projects for the used external loaders. So you will be able to recompile them for your toolchain also.

Best Regards,

Karim

Hi Karim,

Thanks for the response.

I have the STM32CubePpogrammer tool loaded and have tried using the 'GFX01M2_HelloWorld.bat' batch file. I placed 'MX25L6433F_GFX01M2_STM32G0.stldr' into the Binary directory. I still get an error. See log below
