Has anyone ever succeeded booting tftp via a serial interface?
I configured R1 as tftp-server to provide its flash:<ios-image>.
R1 is connected to R2 by a serial DB60-DB60 crossover cable.
R1 is DCE(192.168.2.10) and R2 is DTE.
R2 has a backup ios image on its flash in case it cannot boot tftp. Both interfaces are setup in startup-config. Both routers are 3620.
I power up R1 and a couple minutes later power up R2.
R2 goes directly into rommon, and when I hit boot, it boots from flash even though BOOT=tftp:c3620-ik9o3s7-mz.123-22.bin 192.168.2.10,12;
Here are some console outputs.

Does anyone have information on the exact boot sequence on a 3620 platform?
I am suspecting this platform's ROM cannot initialize serial interfaces,
which is why I tried (with no good result) to put "boot bootstrap flash:c3620-i-mz.123-17a.bin" before "boot system tftp ..." in order to boot flash first then tftp.
Note that rommon on 3620 does not have "tftpdnld" like 26xx.
I would appreciate any help/advice.
Thanks.
SCD
