Fladh Loader for Nucleo-G474RE / X-Nucleo-GFX01M2

[PBeur.1]

I'm using Nucleo-G474RE  + X-Nucleo-GFX01M2

I downloaded the X-Cube-DISPLAY package

I cannot find a flash loader file for the Nucleo-G474RE in the ExternalLoader folder. See below screenshot

Where to find an ExternalLoader file or can I use one of the below ones?

None of these are likely to work as they are board and architecture specific

I'll look to port the Macronix loaders to the G4 in the next several days as time/resources permit

The GFX02Z1 (NUCLEO-144) ones live here

I need to post the H7 ones

Hi Tesla
Thanks for you quick respond and offered help.
Just to be sure: please generate flash loader to be used with Nucleo-G474RE board
(or is this same for all STM32G4xx micro's?)
Waiting for your file

Mainly its the HAL libraries, but secondarily there are multiple QUADSPI pin combinations. I'll have to look at what the NUCLEO implements, or if it is just SPI pins.

The NUCLEO-144's at least had defined QUADSPI pins on the headers

Hi Tesla
According the schematic of the GFX01M2 board it is SPI (only)
Same info can be found in UM2750

Sure, I understand that, but its whether it uses QUADSPI_D0 and QUADSPI_D1 pins that would allow for the QUADSPI controller to work in 1-bit mode.

Dear Tesla
Any idea of you will succeed to create the flash loader file for the Nucleo-G474RE board still this week?

Making progress. I have some NUCLEO-G474RE in hand and have a BSP reading, writing and erasing the MX25L6433F successfully.

In the process of porting a G4 GNU project for the loader.
