I'm trying to enable the UBI-support in U-Boot (later intending to also enable the UBIFS-support). This is on a AT91SAM9260-based system. I've verified the same behaviour using both the at91sam9260ek_nandflash_config and a forward-ported patch for the Olimex sam9_l9260 board. Currently I'm concentrating on the at91sam9260ek_nandflash_config, as this one is in the U-Boot repository.
However, once I enable the UBI-support, the nand-flash chip is not detected... I've tried to trace the problem, and I've found that it is timer-related.
Which options did you define to enable UBI? apollon.h should be helpful as an example here.
Ah, I see them in your patch below. Looks ok on first glance.
It seems that once I enable CONFIG_CMD_UBI, the timer does not work (the debug-printf in the get_ticks()-function in the supplied patch is not printing). If I comment out CONFIG_CMD_UBI, U-Boot continously prints stuff like: Debug: timestamp=6 Debug: timestamp=10215 Debug: timestamp=21556 which is expected.
I'm compiling by running: make clean make at91sam9260ek_nandflash_config make and then flashing u-boot.bin to the board.
The supplied patch works, unless the '#define CONFIG_CMD_UBI 1' is uncommented, in which case the get_ticks function in cpu/arm926ejs/at91/timer.c never seems to be called. I've sofar been unable to understand why.
Strange. This should have nothing to do with UBI at all. Sorry I have no clue where this problem is coming from. Perhaps a "sleeping" issue that is triggered by larger image size?
Best regards, Stefan
