AM4376: RTOS NAND writer needed

Part Number: AM4376

Hi,

customer bings up his board and need to program the NAND flash with his SW.

For his app he used TI-RTOS, not Linux.

In actual AM437 SDK he only found NAND flash write for AM335x ?  …pdk_am437x_1_0_10 ...packages\nand-flash-writer_AM335x

Where is the appropriate tool he needs for AM437 ?

    DJ-NG,

    Sorry for the delayed response. NAND boot on AM437x is not a very widely used boot mode and from the Schematics it appears that GP EVM has a NAND flash but it shares lines with the eMMC interface. We provide the NAND flash writer only for AM335x as we support only NAND boot in the SDK secondary bootloader for AM335x GP EVM as listed here:

    processors.wiki.ti.com/.../AM437x

    GPMC IP is same between AM473x and AM335x but we cannot use the AM335x NAND flash programmer on AM437x due to platform specific dependences like pinmux and NAND device type/geometry differences. There is some porting effort required but this is limited to setup up the correct pinmux for GPMC & ELM pins and to make sure that the NAND geometry of the flash used matches with what is used in the AM335x NAND flash writer.

    Regards,
    Rahul
