/boot/uEnv.txt ignored (1 reply)

I have a FAT partition on a USB stick which is not being read using normal envs. Can't understand why...

envs:-

uenv_addr=0x810000
uenv_import=echo importing envs ...; env import -t $uenv_addr $filesize
uenv_init_devices=setenv init_usb "usb start";  setenv init_ide "ide reset";  setenv init_mmc "mmc rescan"; for devtype in $devices; do run init_$devtype; done;
uenv_load=run uenv_init_devices; setenv uenv_loaded 0; for devtype in $devices;  do for disknum in 0; do run uenv_read_disk; done; done;
uenv_read=echo loading envs from $devtype $disknum ...; if load $devtype $disknum:1 $uenv_addr /boot/uEnv.txt; then setenv uenv_loaded 1; fi
uenv_read_disk=if test $devtype -eq mmc; then if $devtype part; then run uenv_read;  fi; else if $devtype part $disknum; then run uenv_read; fi;  fi
usb_ready_retry=15

If i stop autoboot and enter:-

setenv load_bsdenv 'usb start; load usb 0:1 0x810000 /boot/uEnv.txt; env import -t 0x810000 $filesize'
setenv boot_bsd 'run load_bsdenv; boot'

and then run:-

run boot_bsd

I get:-

uBoot clearly sees the disk:-

What should I change so that /boot/uEnv.txt on this USB stick is read automatically?
