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):
https://github.com/NXPmicro/mfgtools
https://community.nxp.com/t5/i-MX-Processors/kobs-ng-imx-kobs-for-IMX6UL/m-p/788588
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
i.MX 6ULL Applications Processor Reference Manual
Best regards
