It seems that some benign operations in U-boot cause it to abort. For example,
I can type "printenv", or "printenv bootcmd", but if I type "printenv findfdt"
or "printenv uname_boot", I get this:
=> printenv uname_boot
uname_boot=setenv bootdir /boot; setenv bootfile vmlinuz-${uname_r}; if test -e
mmc ${bootpart} ${bootdir}/${bootfile}; then echo loading
${bootdir}/${bootfile} ...; run loadimage;setenv fdtdir /boot/dtbs/${uname_r};
if test -e mmc ${bootpart} ${fdtdir}/${fdtfile}; then run loadfdt;else setenv
fdtdir /usr/lib/linux-image-${uname_r}; if test -e mmc ${bootpart}
${fdtdir}/${fdtfile}; then run loadfdt;else setenv fdtdir
/lib/firmware/${uname_r}/device-tree; if test -e mmc ${bootpart}
${fdtdir}/${fdtfile}; then run loadfdt;else setenv fdtdir /boot/dtb-${uname_r};
if test -e mmc ${bootpart} ${fdtdir}/${fdtfile}; then run loadfdt;else setenv
fdtdir /boot/dtbs; if test -e mmc ${bootpart} ${fdtdir}/${fdtfile}; then run
loadfdt;else setenv fdtdir /boot/dtb; if test -e mmc ${bootpart}
${fdtdir}/${fdtfile}; then run loadfdt;else setenv fdtdir /boot; if test -e mmc
${bootpart} ${fdtdir}/${fdtfile}; then run loadfdt;else if test -e mmc
${bootpart} ${fdtfile}; then run loadfdt;else echo; echo unable to find
[dtb=${fdtfile}] did you name it correctly? ...; run
failumsboot;fi;fi;fi;fi;fi;fi;fi;fi; setenv rdfile initrd.img-${uname_r}; if
test -e mmc ${bootpart} ${bootdir}/${rdfile}; then echo loading
${bootdir}/${rdfile} ...; run loadrd;if test -n ${uuid}; then setenv mmcroot
UUID=${uuid} ro;fi;run mmcargs;echo debug: [${bootargs}] ... ;echo debug:
[bootz ${loadaddr} ${rdaddr}:${rdsize} ${fdtaddr}] ... ;bootz ${loadaddr}
${rdaddr}:${rdsize} ${fdtaddr}; else run mmcargs;echo debug: [${bootargs}] ...
;echo debug: [bootz ${loadaddr} - ${fdtaddr}] ... ;bootz ${loadaddr} -
${fdtaddr}; fi;fi;
