Problem STM32H743IIT QSPI with W25Q128J and External Loader
Hey,
I have a STM32H743IIT Board with an QSPI W25Q128J Flash, i use LTDC and LVGL.
I want to store my pictures in the Flash Memory, but i have some Problems with the External Loader or the Mapping, or something.
The Flash workes fine, when i Write a buffer and Read a Buffer from the Program itself.
I'am a little confused, in the reference guide from the STM32H743IIT, is the Bank 1 located at 0x60000000, but in some examples, are the address 0x90000000 used.
I tried with the CubeProgrammer and the Loader "M29W128GL_STM32H743I-EVAL", here is the Pagesize 0x10, and Startaddress 0x60000000, with these can i erase the complete external memory without errors, but the Pagesize of the W25Q128J is 0x100 (256) ....
Download from STMCubeIDE don't work, i get the Error:

my test file to upload is ca 32 kb...:
const __attribute__((section(".extFlash"))) uint8_t img_logo_map[] = {
0x1a,0x17,0x15,0xff,0x1a,0x17,0x15,0xff,0x1a,0x17,0x15,0xff,0x1a,0x17,0x15,0xff,0x1a,0x17 .......};Is there a W25Q128J Loader for the STM32H743 with QSPI ?
