B-U585I-IOT02A with MX25LM51245G to store and retrieve .bin file using filex and levelx.

[RK.15]

Hello ST community,

I am developing an application based on B-U585I-IOT02A. In this I am using the MX25LM51245G which is on board NOR flash connected via OCTOSPI. The functionality is to save and retrieve a .bin file from the NOR flash. Please let me know how can we achieve the same.

Regards

Hello @Community member​ ,

I advise you to get inspired form the Fx_NoR_Write_Read_File example available in STM32CubeU5 package.

This example may help you by following the instructions in the readme file.

With FatFS we'd use 4KB sectors to match the erase sector/page size of the QSPI/OSPI devices.

NOR Flash isn't particularly fast, and writes will require an erase.
