We are using this driver with CSB272 and CSB472 (both PPC405 based boards).

The driver works OK on CSB272 where flash is setup as 2 side-by- side chips each x16 and accessed via a 32 bit CS.

However, on CSB472 we have some apparently minor issue somewhere. The flash is setup as 1 chip of x16 and accessed via a 16 bit chip select. The protect on/off, erase commands work well. cp command also work OK but after the flash write is completed it leaves the flash array in command mode instead of returning to read mode.

The workaround for now is to reset the board after programming or issue a protect on/off command.

The flash chip is an Intel 28F640 and I've sync to U-Boot CVS last monday.

Has anyone seen this problem, made a patch? I've posted about this before a few months ago but there was more pressing issues to deal with. If someone has solved this problem and a patch is in pipeline, I would like to try it otherwise I need to get my hands dirty to find out why the array is left in command mode.

Best regards, Tolunay
