Hi,
It seem that I have found the root cause of the problem.
This board in qemu is set in this way, that device width is set to 2 and
interface to 4.
That is why CFI driver in u-boot calculates wrongly sector size (
because size ratio variable was wrong ),
so in the end every odd sector (counting from 0 ) was not available.
I've changed vexpress board code in qemu and for now it is working.
I do not have real vexpress board to check if the root cause is u-boot
or qemu,
but i think CFI driver i popular so propapbly there is something wrong
in qemu site.
Regards,
Marcin

Hi Stefan,
I've changed malloc pool size to 2MiB and nothing changed.
I've also disabled UBIFS support and that does not make any changes.
Still after qemu restart u-boot can not attach to ubi device.
Regards,
Marcin

I want to test some UBI fs behavior in U-Boot using qemu and
vexpress_ca9x4
board ( U-Boot 2015.1)
To tst UBI I added lines to vexpress_ca9x4.h:
#define CONFIG_MTD_DEVICE /* needed for mtdparts commands */
#define CONFIG_MTD_PARTITIONS /* needed for UBI */
#define CONFIG_FLASH_CFI_MTD
#define MTDIDS_DEFAULT "nor0=flash0-0"
#define MTDPARTS_DEFAULT "mtdparts=flash0-0:1m(empty),10m(ubi),-(rest)"
#define CONFIG_LZO /* needed for UBI */
#define CONFIG_RBTREE /* needed for UBI */
#define CONFIG_CMD_MTDPARTS
#define CONFIG_CMD_UBI
#define CONFIG_CMD_UBIFS
#define CONFIG_FIT
also I've changed malloc pool size to 512kB in vexpress_common.h:
#define CONFIG_SYS_MALLOC_LEN (CONFIG_ENV_SIZE + 512 * 1024)
Without looking deeper into your mail, I would recommend to increase
the malloc size to at least 2MiB and test again.
Thanks,
Stefan
