    Hi Marius, Looking through the NAND Flash examples, why did the developer not use higher level calls for SPI/QSPI, like HAL from ST or the SPI peripheral driver from Nordic, etc. Working at such a low level doesn't help illuminate the functionality…

    Hi Marius, Let me give you and example. The example FS_NAND_HW_QSPI_STM32H743_SEGGER_QSPI_Flash_Evaluator.c. Clearly this software runs on your "(Q)SPI Flash Evaluator” board, but what NAND Flash part did they put on one of the adapter board when they…

    H Marius, Thank you for the info. I'm working on the FS_NAND_HW_TYPE_SPI type driver, but it would be helpful if I could learn how your example implementations work by referencing the datasheets of the NAND flash devices used in those examples. The part…

    I’m mentoring a student from Georgia Tech who is helping develop a biomedical device that uses NAND flash, specifically Toshiba/Kiokia TC58CVG2S0HRAIG, which in the list of Universal drivers supported by Segger. How do I use the Universal driver to…

    If we use FAT32 format for NAND flash, the flash will wear out quickly because we are updating the directory structure each time we write a page of data. We are using a 512MB flash device and storing 400MB each day, so there isn’t a lot of space for…
