Other Parts Discussed in Thread: 66AK2L06
Hello E2E Community,
We're working with the 66AK2L06 on the XEVMK2L06 and are in the process of making sure we can successfully flash the NOR and NAND on the board. The NOR successfully flashes and boots, and the NAND successfully flashes as well but fails to properly boot. The steps we use to flash the NAND are as follows:
1. We set the EVM to DSP No Boot (1111)
2. We set the proper environment variables and use the program_evm.js script to format the NAND
3. We use the program_evm.js script to flash the NAND. This completes successfully after the changes to the NAND writer as described here
4. We then turn the board off and set it to SPI NOR Boot (0010) and turn it back on
5. Uboot's autoboot attempts to load the Linux kernel in the NAND
6. We encounter the following error that repeats for every PEB:
ubi0 error: ubi_io_read: error -74 (ECC error) while reading 64 bytes from PEB 2:4096, read 64 bytes
Any ideas on where this error comes from? Is this a problem with how we're flashing the UBI image, the U-boot environment, or something else entirely?
Thanks,
Eldrick
