ERROR about ETFS nand system in bsp
Hello,Now we are using the ETFS nand system in the bsp "bsp-nto650-ti-am335x-evm-sp1-trunk-201211211248". In the
previous days all of our products run ok, but some of the products suddenly have an "ETFS nand system" error in these
days. We don't know why the error happen. When i run "fs-etfs-omap3530_micron -D gpmc=0x50000000 -m /app" again, the
products with the error print:
Starting etfs driver2...
fs-etfs-omap3530_micron: readtrans BADBLK on cluster 38848
fs-etfs-omap3530_micron: readtrans BADBLK on cluster 190144
fs-etfs-omap3530_micron: readtrans BADBLK on cluster 504384
fs-etfs-omap3530_micron: No filesystem detected. Entering stopped mode.
fs-etfs-omap3530_micron: Unable to initialise ETFS systems (Corrupted file system detected)
when the error happen, if I run "fs-etfs-omap3530_micron -D gpmc=0x50000000 -e -m /app", the ETFS nand system will
resume to use.
I have the following questions to ask for help:
1.How the nand driver program judge if it detected the Corrupted file system? Does the driver read some fixed
position of the nand block?
2.when I run "fs-etfs-omap3530_micron -D gpmc=0x50000000 -m /app -vvv", it print:
Readtran 7672: 0 491008 ret 2 -> 16937692 0 8,3688

Readtran 7685: 0 491840 ret 2 -> 16937692 0 8,3688
what each of the below number means ?
3.How to find the reason of this error? Maybe a power failure? I have tested with a lot power failure, but the
error didn't happen again.
thank you very much!
