[U-Boot] i.Mx6q u-boot stuck
Hi,
i have a problem with my custom board.
I created my custom u-boot and, now, i would like load automatically the kernel by CONFIG_BOOTCOMMAND.
#define CONFIG_BOOTCOMMAND \
"mmc dev ${mmcdev};" \
"if mmc rescan; then " \
"echo test1; " \
"else echo test2; fi; "
Because i have the "if" condition, i enabled the CONFIG_HUSH_PARSER=y into deconf file.
Adding this CONFIG, the u-boot stuck
CPU: Freescale i.MX6Q rev1.5 996 MHz (running at 792 MHz) CPU: Extended Commercial temperature grade (-20C to 105C) at 26C Reset cause: POR I2C: ready DRAM: gd->ram_size: 1073741824 DRAM test not implemented! 1 GiB
Whitout the definition CONFIG_HUSH_PARSER=y i have the following result:
CPU: Freescale i.MX6Q rev1.5 996 MHz (running at 792 MHz) CPU: Extended Commercial temperature grade (-20C to 105C) at 28C Reset cause: POR I2C: ready DRAM: gd->ram_size: 1073741824 DRAM test not implemented! 1 GiB

Why, if i enable the CONFIG_HUSH_PARSER=y, the u-boot stuck? ------------------------------ *Ing. Fausto Sessego* *R&D Hardware & Software Engineer* info mob

CONFIG_HUSH_PARSER=y is enabled in many mx6 boards without issues.
It is difficult to see what is wrong without seeing your patch adding the support for your board.
Make sure you are using the latest U-Boot code and check what other mx6 boards are doing.
Hi Fabio,
in attachment there are my configuration files.
I started from SabreSD and i changed very minimal parts.7
Could you check if you see any error in my files?
thanks

It would be better to submit a proper support for your mx6 board.
You seem to call it mx6board, but in your defconfig you have:
CONFIG_TARGET_MX6BAORD=y
Looks like a typo.
