Hi everyone,

I'm trying to boot u-boot from uEnv.txt. And I've got a problem. I'm
using zynq_picozed_defconfig

The problem is I've got this error after the uEnv.txt is read:
eth0: ethernet@e000b000
Hit any key to stop autoboot:  0
Device: sdhci@e0100000
Manufacturer ID: 3
OEM: 5344
Name: SL16G
Tran Speed: 50000000
Rd Block Len: 512
SD version 3.0
High Capacity: Yes
Capacity: 14.8 GiB
Bus Width: 4-bit
Erase Group Size: 512 Bytes
reading uEnv.txt
754 bytes read in 15 ms (48.8 KiB/s)
Loaded environment from uEnv.txt
Importing environment from SD ...
test - minimal test like /bin/sh

test [args..]

It seems to be that fail to run the script:

uenvboot=if run loadbootenv; then echo Loaded environment from ${bootenv};
run importbootenv; fi; if test -n $uenvcmd; then echo Running uenvcmd ...;
run uenvcmd; fi

When the test -n $uenvcmd is executed, but I don't understand why, because
when I execute the script, run uenvcmd runs fine.

Any suggestion? It seems to be when the console is ready the test function
works fine, but before it fails.

Best regards.
