how is it possible to upgrade a C801 //with TinyROM-1.2(2)// to IOS 12.3

how is it possible to upgrade a C801

//with TinyROM-1.2(2)// to IOS 12.3

C801: TinyROM-1.2(2)

FLASH : 8MByte

new IOS : c800-osy6-mw.123-3a.bin = 6.2MByte

so i have to delete the old IOS (2,5 - 3 MByte)

but this is only possible in boot/rommon mode

(no deleting of the actually active IOS possible)

so i have to do the boot/rommon "upload" or "boot" command (see below)

anything wrong with my upgrade tasks ???

C801-output:

boot# list

tftp: failed (5 seconds), "buffer overflow"

boot: failed, "buffer overflow"

!!! "BUFFER OVERFLOW" !!!

what does this error message mean ???

is this a problem of TinyROM-1.2(2)

i checked differend TFTP-Servers,

but always the same error

TFTP transfers is always good for 14/15% transmission.

is there any URL or hint for me ???

anything wrong with my upgrade tasks ???

Hi,

But this is not any error with TFTP server. If this were a TFTP server problem, it could have stopped at the beginning only, not at 15%.
