External flash nucleo-F746ZG with w25q128jv

[Stlinkos]

Hello, 

I have a problem when i try to load a bin file using External flash.

 

I created my own external flash with w25q128vj and nucleo F746ZG .When i try to load a bin file with stm32programmer its work only if the bin file is smaller than 128kb. 

Someone have any idea about this problem :

this is what i can see in stm32programmer.

Hello @Stlinkos ,

Could you please check the memory parameters in Dev_Inf.c file like: Device size and  Programming Page Size.

Thank you.

You can output diagnostic output via a convenient serial UART or LEDs on the board to understand what's going on internally.

Would suggest testing the code externally in an application or framework you can drive and debug in a more usual way. Once tested there move to the External Loader model.

Data pages can only be written up to 256 bytes at a time, and those need to be page aligned, and not cross page boundaries.

This should be a suitable pin configuration for a NUCLEO-144 based fixture using the normal QSPI pins.

Hello @Tesla DeLorean,

 

i tried with the example https://github.com/cturvey/stm32extldr/blob/main/f7_w25q128/CLIVEONE-W25Q128_STM32F7XX-PB2-PB6-PD11-PD12-PE2-PD13.stldr  and i had this error  when i try to downlaod a bin file(i tried with a lot of  bin file i have "Error: Data mismatch found at address 0x90000000 (byte = 0xXX instead of 0xXX") :

hardware config :

• Chip Select (CS): PB6
• Data Input (DIN): PD11
• Data Output (DOUT/MISO): PD12

Try this, should be a 2-pin variant  https://github.com/cturvey/stm32extldr/blob/main/f7_w25q128/CLIVEONE-W25Q128_STM32F7XX-PB2-PB6-PD11-PD12.stldr

If this doesn't work I'll need to break out a fixture and do some more testing

[Pavel A.]

@Stlinkos So look... you have these pins NOT connected: PE2, PD13. The stldr expects them to work.

 

[Stlinkos]

Hello @Tesla DeLorean , @Pavel A. , @KDJEM.1 ,

 

Finally, i connected: PE2, PD13 and used https://github.com/cturvey/stm32extldr/blob/main/f7_w25q128/CLIVEONE-W25Q128_STM32F7XX-PB2-PB6-PD11-PD12-PE2-PD13.stldr. 

The load and read work if i use stm32programmer (i create and bin file, load it and read the right data) but if i use stm32cubeIde and touchgfx i have problem with the displaying.

I add the stdlr file in my project and setting the run configurations like : 

The datas are in the flash memory : 

The configuration of my touchgfx is 

The Background image is not in the flash it works but the others in flash doesn't.

this what i have

Do you have any idea why my image in flash is wrong.
