Hi I am using AM4378 and S34ML02G1 in custom board.
I have loaded and running boot code using CCS.
I am able to get boot prompt and after that want to perform NAND read write.
Sequence followed for NAND read are as follows;
=> nand erase.chip
NAND erase.chip: device 0 whole chip
Erasing at 0xffe0000 -- 100% complete.
OK
=> nand read 0x80000000 0x400000 0x40000
NAND read: device 0 offset 0x400000, size 0x40000
262144 bytes read: OK
=> nand write 0x80000000 0x400000 0x40000
NAND write: device 0 offset 0x400000, size 0x40000
omap-elm: uncorrectable ECC errors
omap-elm: uncorrectable ECC errors
NAND write to offset 400000 failed -5
0 bytes written: ERROR
Command failed, result=1
I have verified the READ ID's and it is as expected as per datasheet of NAND
"01h DAh 90h 95h 44h"
What could be the possibilities of getting uncorrectable ECC errors?
Please suggest if I am missing anything. Your support is appreciated.
Thanks
Sai
