Linux/AM3351: How to use Uniflash

Linux/AM3351: Nandflash

Tool/software: Linux

Hi TI,

In my new project, I use MT29F1G08 NAND flash,  AM3351, SDK7.0, Now, the uboot can run normally, but the kernal cann't boot. 

I changed pin mux and gpmc in dts, but it cann't probe the nand. So, I don't know what to do!  I really hope to get your help. Thanks a lot.

    Sorry, SDK 7.0 is obsolete since more than 3 years ago, and is no longer supported by TI. Please move to the new Processor SDK: www.ti.com/.../PROCESSOR-SDK-AM335X

    Hello yongpam,

    Please, try to find out why the nand_get_flash_type function exits with error and the NAND device is not found.
    [ 1.339823] nand: No NAND device found

    <Processor SDK>/board-support/linux-<version>/drivers/mtd/nand/nand_base.c

    	/* Read the flash type */
	type = nand_get_flash_type(mtd, chip, &nand_maf_id,
				   &nand_dev_id, table);

	if (IS_ERR(type)) {
		if (!(chip->options & NAND_SCAN_SILENT_NODEV))
			pr_warn("No NAND device found\n");
		chip->select_chip(mtd, -1);
		return PTR_ERR(type);
	}

    Best regards,
    Kemal

    Dear TI，
    The problem has been resolved, it caused by incorrect SYSBOOT[15:14], i used 25M oscillator, but SYSBOOT[15:14] be initialied 11b, so kernel clock be set to 26M.

    Yes, this is correct. Now I remember the similar issue was addressed in this, this and this thread. Thank you for providing the resolution and reminding me this.
