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.
