Dear Expert
The am3358 system we use now has a question for you
Question 1: start the options, boot9. early we are high level, and later modify to low level
In the document, the table 26-7. sysboot configuration pins is described in the document
Boot9= 0 ecc done by ROM
1 ecc handly by nand
We have a board card that can't start the system, and the boot9 is changed from the original 1 to 0. the printing information is as follows:
For example: "you can't do it."
Texas Instruments Revision detection unimplemented
Booting from nand...
Ecc pos 195 mask 3
This information is ecc pos 195 mask 34, which is not available in uboot, is it a CPU that has a program to handle?
Question 2: change the boot9 to 0, and you can start the system, but you can change the boot9 back to 1and still can't start the system
This shows that ecc is just checking for data, but it does not modify the error data in nand
Is that so?
Question 3: in the boot area, there is information on ecc pos 195 mask 3ps, which shows that nandflash has a data error
The uboot area is simply read-only, how can you make a data error, which is impossible to understand
I don't know if there was any such problem
Question 4: because ecc does not correct data in nandflash
So over time, nandflash has more data errors
So the ecc can't be corrected, and it will not be able to start the system
Do you know what to do to avoid the uboot area data error in nandflash, or to fix data errors in nandflash
The attachment is to change the boot9 from the original 1 to 0, and the startup process is printed with information
The model nandflash USES is the mt29f4g08abadawp of micron
