we have designed a custom hardware based on the i.mx7.
Both eMMC and NAND are available as mass storage.
eMMC is connected to the SD1 interface (and SPI2 Interface to get a total of 8 data lines).
NAND is connected to SD3+SAI1 and shall be used as the primary boot source.
JTAG is available.
How do I get my uboot/linux/device tree stored in NAND?
Most articles/posts I find recommend to use an SD card and uboot to copy the boot image to NAND. But theres no SD card here. I guess an emulator or is needed to transfer the file through JTAG? If this is correct: What kind of emulator may I use? Do I need anything besides the MFG Tools? Any other software? Any hardware?
