Hi all,
We have hit the following issue in a board with 2 flash banks.
First I set some env variable in U-boot, using fw_setenv, then immediately I switch the banks. But as the buffers have not yet been flushed to the mtd driver, the bank switching leaves the flash in corrupted state.
Isn't this a bug in the respective MTD driver then? You should be able to open as many file-descriptors to different mtd devices as you like and be able to operate on them simultaneously. Or doesn't it work like that?
I ve modified the fw_env.c file to open the mtd O_SYNC and it works fine.
If it is OK I can submit a patch for this.
