Hi all,
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

Why, if i enable the CONFIG_HUSH_PARSER=y, the u-boot stuck?
Hi Fausto
please refer to attached Porting Guide and use nxp uboot
http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/tree/?h=imx_v2016.03_4.1.15_2.0.0_ga
Also as this is specific uboot question it may be posted on uboot mail list
Best regards
igor

Ok, i posted into u-boot mailing list my problem.
I have another question:
I configured all peripehricals / IO into u-boot.
I know there is the possibility to call the number 0x80000000 into kernel to get the previous setting:
for example
&iomuxc { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_hog>; hog { pinctrl_hog: hoggrp { fsl,pins = < /* gpio-leds */ MX6QDL_PAD_EIM_D28__GPIO3_IO28 0x80000000 MX6QDL_PAD_EIM_A25__GPIO5_IO02 0x80000000 /* J11 pins 32, 34, 36, 38 */ MX6QDL_PAD_CSI0_DAT8__GPIO5_IO26 8 MX6QDL_PAD_CSI0_DAT9__GPIO5_IO27 8 MX6QDL_PAD_KEY_COL1__GPIO4_IO08 8 MX6QDL_PAD_KEY_ROW1__GPIO4_IO09 8 >; }; }; };
In this way, i avoid to configure again the IO.
What do you suggest?
To configure all pin into u-boot and after to call 0x80000000 for all IO into kernel, or to configure again?
What is it the correct procedure?
thank you
