Hi,
I have strange phenomena.
I have DM365 baaed board.
In some boards (Not all of them), I get this strange case:
Accessing the NAND (Erase/write), like with saveenv command, followed by
Ethernet access (TFTP/PING) stuck the SW.
Accessing the NAND without prior access to ETHERNET works fine.
I tried to debug this with TI code composer studio.
When accessing the NAND, it seems that the CPUs data bus is hung, and I get
the following message from code composer:
Warning:
0x40000020/-1032 @ marker 1022
Warning during: Execution,
The pipeline is stalled owing to 'data bus not ready'
Did you ever encounter such a problem?
Do you know if it is caused by HW problem (Corrupt NAND/DM365), or a fixable
SW bug?
Thanks in advance
Alex
