J-TAG flashing to NAND with iMX6ULL chipset

[kmagi]

Hello All,

I am working on bring-up of the custom board with only J-TAG interface for programming the NAND flash which is with iMX6ULL processor.

I am using the SEGGAR j-link device for programming the NAND flash.

Could you please share me what are the approaches I can follow?

Could you also share me the U-BOOT address location from where the BOOTROM loads it to RAM?

I have 3 MTD memory partitions. First one the raw partition for u-boot. Second UBIFS partition for kernel+root fs and  third JFSS2 for private data.

Best regards,

Kiran

Hi Kiran

unfortunately nxp does not support nand programming through jtag, supported

only option with uuu (and kobs-ng tool):

For ROM addresses one can look at sect.8.7.1 Image Vector Table and Boot Data,

sect.8.5.2.3 Firmware configuration block
