Do you have console output enabled? If yes, then you can (1) get pretty reliable timings very easily by just time-stamping the console output (even with external tools as you read it rom the serial port), and (2) save a LOT of time by disabling it :-)

Yes, I will try that.

OK - then I recommend to _increase_ teh image size by NOT compressing the Linux kernel. This way we get the fastest boot times on most systems. Also, turn of checksum verification (setenv verify no).

Argh, "setenv verify no" ! Ah, I turned off

if (verify) { puts (" Verifying Checksum ... "); if (crc32 (0, (char *)data, len) != ntohl(hdr->ih_dcrc)) { printf ("Bad Data CRC\n"); SHOW_BOOT_PROGRESS (-3); return 1; } puts ("OK\n"); }

instead and I think this also disables the checksum verification when normal booting...
