Nand boot with evk board

guochgz — Fri, 02 Aug 2019 08:43:11 GMT

hello,

I have removed the qspi flash from evk board and solder U302 W29n01hv NAND FLASH on the EVK board, that the flash pins is the same with MT29G08CBADBWP

and now I recompile the uboot follow the steps:

1: make distclean;

2: make mx6ull_14x14_evk_nand_defconfig

3: make

and replaced the firmware/u-boot-imx6ull14x14evk_nand with u-boot-dtb.imx, and the same with files u-boot-imx6ull14x14evk_nand.imx

then I got the log like this:

so It seems Nand has been recognized, but not configured correctly?

EXTENDED_ID_NAND("NAND 128MiB 3,3V 8-bit", 0xF1, 128, 0x0),

should I added those item like this:

2 },

Hi 国承张

one can try to follow steps described on

hello, igor.

I have just follow that steps, now the issue is uboot can not work with nand boot while in nand bbt funtion. Maybe this issue is related to the nand configs or uboot bad block table function .

I have added comments in search_bbt function:

got log like this:

Re: Nand boot with evk board

igorpadykov — Mon, 05 Aug 2019 05:15:48 GMT

Hi 国承张

one can check if there is entry for this nand in nand_ids.c file

nand_ids.c\nand\mtd\drivers - uboot-imx - i.MX U-Boot

Best regards
igor

Re: Nand boot with evk board

guochgz — Mon, 05 Aug 2019 05:40:04 GMT

yes, there is one item matched.

EXTENDED_ID_NAND("NAND 128MiB 3,3V 8-bit", 0xF1, 128, LP_OPTIONS),

Re: Nand boot with evk board

igorpadykov — Mon, 05 Aug 2019 06:43:35 GMT

one can recheck if correctly used kobs-ng init, it updates FCB/DBBT.

Best regards
igor

Re: Nand boot with evk board

guochgz — Mon, 05 Aug 2019 06:57:25 GMT

I have no idea about kobs-ng init, do you show me more details?

I have added item in nand_ids.c

and got log like this:

Does this means I need to disable this option?

nand->bbt_options = NAND_BBT_USE_FLASH | NAND_BBT_NO_OOB;

and NAND_ECC_INFO(1, SZ512), I am not sure that this configuation is correct. can you help me check this?

or NAND_ECC_INFO(1, 528) is correct?

thanks very much.

hello.

I tested it with a lower version(L4.1.15) of uboot and found the results were different

the nand driver needs two changes, nand_ids.c and READID function.

so what need to do next? replace firmare/zImage ?

Re: Nand boot with evk board

igorpadykov — Tue, 06 Aug 2019 11:27:12 GMT

it is necessary to apply kobs-ng init on some step as in example on

Currently, the problem points to the erase problem of Nand flash. When the 60h, d0h command is executed, the 70h command is used to read the status, and the value returned is 0xFF, not 0x40.

log is：
