libusb error while flashing iMX6ULL NAND device using UUU

asurti9 — Sat, 03 Feb 2024 12:00:51 GMT

Hello NXP team,

I am trying to flash my custom devicehaving NAND flash. It is based on iMX6ULL EVK design

I have downloaded the YOCTO source and built it with UBOOT_CONFIG = "nand" in local.conf.

The image generated is u-boot-nand-2023.04-r0.imx

When I try flashing the device with the above mentioned u-boot, I am facing below error:

sudo uuu -v -V -pp 1 -b nand u-boot-nand-2023.04-r0.imx uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.5.21-0-g1f42172 Build in config: Pctl Chip Vid Pid BcdVersion ================================================== SDPS: MX8QXP 0x1fc9 0x012f [0x0002..0xffff] SDPS: MX8QM 0x1fc9 0x0129 [0x0002..0xffff] SDPS: MX8DXL 0x1fc9 0x0147 SDPS: MX28 0x15a2 0x004f SDPS: MX815 0x1fc9 0x013e SDPS: MX865 0x1fc9 0x0146 SDPS: MX8ULP 0x1fc9 0x014a SDPS: MX8ULP 0x1fc9 0x014b SDPS: MX93 0x1fc9 0x014e SDP: MX7D 0x15a2 0x0076 SDP: MX6Q 0x15a2 0x0054 SDP: MX6D 0x15a2 0x0061 SDP: MX6SL 0x15a2 0x0063 SDP: MX6SX 0x15a2 0x0071 SDP: MX6UL 0x15a2 0x007d SDP: MX6ULL 0x15a2 0x0080 SDP: MX6SLL 0x1fc9 0x0128 SDP: MX7ULP 0x1fc9 0x0126 SDP: MXRT106X 0x1fc9 0x0135 SDP: MX8MM 0x1fc9 0x0134 SDP: MX8MQ 0x1fc9 0x012b SDPU: SPL 0x0525 0xb4a4 [0x0000..0x04ff] SDPV: SPL1 0x0525 0xb4a4 [0x0500..0x9998] SDPV: SPL1 0x1fc9 0x0151 [0x0500..0x9998] SDPU: SPL 0x0525 0xb4a4 [0x9999..0x9999] SDPU: SPL 0x3016 0x1001 [0x0000..0x04ff] SDPV: SPL1 0x3016 0x1001 [0x0500..0x9998] FBK: 0x066f 0x9afe FBK: 0x066f 0x9bff FBK: 0x1fc9 0x0153 FB: 0x0525 0xa4a5 FB: 0x18d1 0x0d02 FB: 0x3016 0x0001 FB: 0x1fc9 0x0152 FB: 0x0483 0x0afb Run built-in script: uuu_version 1.2.39 # @_flash.bin | bootloader # @_image [_flash.bin] | image burn to nand, default is the same as bootloader # This command will be run when i.MX6/7 i.MX8MM, i.MX8MQ SDP: boot -f u-boot-nand-2023.04-r0.imx # This command will be run when ROM support stream mode # i.MX8QXP, i.MX8QM SDPS: boot -f u-boot-nand-2023.04-r0.imx # These commands will be run when use SPL and will be skipped if no spl # SDPU will be deprecated. please use SDPV instead of SDPU # { SDPU: delay 1000 SDPU: write -f u-boot-nand-2023.04-r0.imx -offset 0x57c00 SDPU: jump # } # These commands will be run when use SPL and will be skipped if no spl # if (SPL support SDPV) # { SDPV: delay 1000 SDPV: write -f u-boot-nand-2023.04-r0.imx -skipspl SDPV: jump # } FB: ucmd setenv fastboot_buffer ${loadaddr} FB: download -f u-boot-nand-2023.04-r0.imx FB: ucmd if test ! -n "$fastboot_bytes"; then setenv fastboot_bytes $filesize; else true; fi # Burn image to nandfit partition if needed FB: ucmd if env exists nandfit_part; then nand erase.part nandfit; nand write ${fastboot_buffer} nandfit ${fastboot_bytes}; else true; fi; FB: ucmd nandbcb init ${fastboot_buffer} nandboot ${fastboot_bytes} FB: Done Wait for Known USB Device Appear...

I tried the prebuilt images from NXP , but it is also giving the same error. I tried the example uuu script as well, with the modifications needed. But I am facing the same issue.

If needed I can share the schematic of our custom board privately to get it reviewed.

Can you please help us resolving the issue?

Thanks!

Hi,

Thank you for your interest in NXP Semiconductor products,

You could try this porting guide but for 6ULL, i.e., you have to make modifications to support 6ULL's nand boot and there are in latest release as:

configs/mx6ull_14x14_evk_nand_defconfig

In that case, you'd take upon the test and update to latest release and latest UUU release, please update how did it went.

Regards

Hello @JosephAtNXP ;

I tried what you suggested, but still I am facing the similar issue.

Can you suggest whether the issue is with the u-boot which I am building or something related to usb driver on host?

Attaching the generated u-boot for your reference.

Thanks!
