Re: [U-Boot] [fw_printenv should open device as O_SYNC]

Dear Ivan,

In message 7ADFACCCB37616458C4A346B2727D3360474A88A@ct11exm66.ds.mot.com you wrote:

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.

What eactly do you mean by "I switch the banks" ? How exactly do you do that? Can you please provide the exact set of commands you are using?

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.

sure. Please submit it so we can see what you are talking about.

Best regards,

Wolfgang Denk
