I created a u-boot for my custom board using the i.MX6ull processor.  I need it to work with NAND flash.

It boots from USB, and I am starting with the default NAND script.  Because it got the error, I added a few commands with my own script.  I added nand info and printenv:

 

FB: ucmd if env exists nandfit_part; then nand erase.part nandfit; nand write ${fastboot_buffer} nandfit ${fastboot_bytes}; else true; fi;
FB: ucmd nand info
FB: ucmd printenv
FB: ucmd nandbcb init ${fastboot_buffer} nandboot ${fastboot_bytes}
FB: Done

 

  
Is nandboot documented anywhere?

Here is the output of NAND info, which seems right to me:

 

Device 0: nand0, sector size 256 KiB
  Page size       4096 b
  OOB size         256 b
  Erase size    262144 b
  subpagesize     4096 b
  options     0x40004200
  bbt options 0x00060000

 


Here is the output of printenv, which is probably showing what is wrong, if I knew where to look:

 

baudrate=115200
bootargs=console=ttymxc0,115200 rdinit=/linuxrc clk_ignore_unused
bootcmd=nand read ${loadaddr} 0x180000 0x1000000;nand read ${fdt_addr} 0x1180000 0x80000;if test ${tee} = yes; then nand read ${tee_addr} 0x1200000 0x100000;bootm ${tee_addr} - ${fdt_addr};else bootz ${loadaddr} - ${fdt_addr};fi

I figured this out.  To get the partition related stuff to work, you need:

CONFIG_MTD_PARTITIONS=y



In the U-Boot configuration.  I had been looking in configs/mx6ul_14x14_evk_optee_defconfig and this does not have MTD partitions turned on.

I added four environmental variables to the uuu.auto script and it boots successfully:

FB: ucmd setenv partition nand0,0
FB: ucmd setenv mtddevname nandboot
FB: ucmd setenv mtddevnum 0
FB: ucmd setenv mtdids "nand0=gpmi-nand"

 

So now I need to figure out what is wrong with my U-Boot build that these are not in my environment.

I assume there must be something wrong with the U-Boot configuration file?
