howto cp to flash
After download zbarebox.bin to /, I wrote it to flash
tftp barebox.bin
memcpy -b -s./zbarebox.bin -d/dev/nor0.root 0 0
Then I dump both:
# md -s /dev/nor0.root 00000000: ffffffff ffffffff ffffffff ffffffff ................ 00000010: ffffffff ffffffff ffffffff ffffffff ................ 00000020: ffffffff ffffffff ffffffff ffffffff ................
# md -s ./zbarebox.bin 00000000: ea00000a eafffffe eafffffe eafffffe ................ 00000010: eafffffe 0000016c eafffffe eafffffe ....l........... 00000020: 65726162 00786f62 23b00000 0002389c barebox....#.8..
No contents in flash, Why?
Another question:
How can I get file size in script?

Hi,
Did you erase the flash ?
You can also directly do a tftp barebox.bin /dev/nor0.your_partition

Have you tried the unprotect command like Eric suggested?

this should work :
tftp barebox.bin
unprotect /dev/nor0.root
erase /dev/nor0.root
cp barebox.bin /dev/nor0.root
or with less operations :
unprotect /dev/nor0.root
erase /dev/nor0.root
tftp barebox.bin /dev/nor0.root
