Every project in this folder for OSPI in H7 chips using CubeIDE compiles with error, Keil complies without errors

I have this code it transfers to 0x90000000 (OSPI) data__IO uint8_t *mem_addr; /* USER CODE BEGIN 2 */HAL_OSPI_MemoryMapped(&hospi1, &sMemMappedCfg) mem_addr = (uint8_t *)(OCTOSPI1_BASE + address);for (index = 0; index < BUFFERSIZE; index++){*mem_ad...

I used thisBSP_OSPI_NOR_Write(uint8_t* pData, uint32_t WriteAddr, uint32_t Size) fromhttps://github.com/STMicroelectronics/stm32-external-loader/blob/main/STM32L4x_boards/MX25LM51245G_STM32L4P5G-DK/Sources/Library/stm32l4p5g_discovery_ospi_nor.c but ...

It looks like simply replacing the QSPI loader files, which are available on github (CubeIDE)but not all is exactly the same.for example the are functions likeOSPI_OctalModeCfg(&hospi1);do I need to call it somewhere ? so far the loader for QSPI is w...

The QSPI is working fine, I can write and read using the standard library.But when using external loader, it can never write the data correctly, though I can read using Cube programmer.this is the data I am getting instead ofI am using the loader fil...

if he is talking LTDC then we would have something like RGB323 format.You would use pins R7, R6, R5, G7, G6, B7, B6, B5. Nobody is using something like this.There is no such a thing.RGB565 is the most popular.a have a few projects connected to 8 bit ...

what kind of display you are talking about ? there are a few of them to use 8 bit data.

You can always use this code to write then enable memory mapped mode later and read from 0x90000000You write to address = 0This code is working on me on H7 chip and same MX25LM5124I had some problems too to write in mapped mode. /* Configure the memo...

I will just put it aside, enough fun for one day. I do not have similar problem with QSPII do not know why but if I read the memory address and write there then it works. Maybe something to take a look at later again.I tried all possible settings in ...

compile errors in STM32Cube_FW_H7_V1.9.0, anybody from STM to comment ?

any idea why it is freezing executing *mem_addr = aTxBuffer[index];

Does anybody have working write routine for OSPI ? STM32H7 MX25LM51245G

are the external loader files for Octo SPI somewhere, github ?

external loader Data mismatch found at address 0x90000000 (byte = 0x88 instead of 0x00)
