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
1 GiB MMC: FSL_SDHC: 0, FSL_SDHC: 1 *** Warning - bad CRC, using default environment
In: serial Out: serial Err: serial Net: FEC [PRIME] Error: FEC address not set.
Hit any key to stop autoboot: 0 switch to partitions #0, OK mmc1 is current device Unknown command 'if' - try 'help' Unknown command 'then' - try 'help' Unknown command 'else' - try 'help' Unknown command 'fi' - try 'help'

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