Hi, everyone.Recently, I want to write the stm32 FTL (Flash Translation Layer) algorithm of NAND flash, but I can’t find any sample code about the FTL algorithm on the Internet. I would like to ask if you have any recommended documents or information...

Hi everyone, this is my first time posting a question.I use the MX25UM51245G OctoSPI Flash memory of the STM32H7B3LI Discovery Board. Use stm32cubeIDE. I have referred to STM32L4 Octo-SPI Application note and STM32H7 Octo-SPI Application note.But I s...

I'm not sure if my answer is correct.You said unable to erase data, maybe you should first erase data -> write data -> read data

Thank you for your help during this time.I deleted all stm32cubeide. STM32Cube regenerates a new stm32cubeide, and the program is not modified at all, so there is no problem at all.It is amazing...

1. The issue with manually driving the NCS pin has been resolved, as I have removed it. However, I am still receiving a reg value of 0.(if (HAL_OSPI_Receive(&hospi1, reg, HAL_OSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK)2. In the sections of OPI_WriteEnab...

The preceding section is configured to use non-DTR mode.While the OPI_WriteEnable and Octal_PollingWEL operations in the subsequent section are performed using DTR mode. The reference source for this is the STM32H7 Octo-SPI Application Note.I have al...

Thank you for your reply.I connected the pin according to stm32H7B3I_Schematic.pdf, and I have repeatedly confirmed that the pin is correct, so it should be correct...The picture below is the pin of stm32cube and STM32H7B3 OctoSPI Flash Schematic pdf...
