Hi,
We are having with AM335x GPMC (NAND) burst access with DMA.
It works normal for 4 word, but above 4, the same data is repeated.
This application won't use any OS, its a bare metal application.
Below is the register settings used for 4/8/16 word.
4 word
GPMC_CONFIG1_3 = 0xF8601201;
8 word
GPMC_CONFIG1_3 = 0xF8E01201;
16 word
GPMC_CONFIG1_3 = 0xF9601201;
Result:
4 Word: Works normal
8 Word: 0 to 3 words are normal, but 4 to 7 words are same as 3rd word
16 Word: 0 to 3 words are normal, but 4 to 15 words are same as 3rd word
3rd word seems to be repeated....
Could you please let me know if there is any settings to be considered
when using GPMC burst access with DMA.
Best Regards
Paddu
