Other Parts Discussed in Thread: AM4378
Hi TI Champs
There's request from Customer who uses 2Gbit NAND for boot device.
They have used 1Gb sucessfully. But their client requested to increase the memory capacity to 2Gb.
Therefore, AM4372 and AM4378s are testing 2Gbit, but they are still not NAND booting.
(With 1 Gbit NAND, NAND boot is working fine.)
As you can see in the log below, the Chip ID is being read as 0xda
This corresponds to the Supported NAND Devices specified in 5.2.6.4.2.3 Device Detection and Parameters in the AM4372 Technical Reference Manual.

As mentioned above, I think NAND support is correct, but I don't know why 1Gb can boot NAND and 2Gb can't boot.
I would like to ask for a detailed review of whether there is any error related to SYSBOOT.
For your information, MLO will proceed normally if you boot to MMC and then perform NAND boot from u-boot.
Therefore, you can verify that it is not written incorrectly to NAND.
(See logs below)
Therefore, it is judged that there is a problem in the process of entering NAND according to the SYSBOOT setting from the ROM code of the CPU.
I ask for your review.
