AS5200 flash - read only


I have 10M ios file , 8M bootflash and 16M flash on an AS5200 machine.

The flash is in read only mode.

How can I change it to read-write mode?

(I've tryed to change the confreg to 0x2101)

Thank you,

Re: AS5200 flash - read only

You need to boot the router from Bootflash using confreg 0x2101 and after that you need to issue "copy tftp flash" to copy/write the new ios file in to flash.

Here is the url which will guide you for step-by-step ios upgrade on AS5200

Here is the procedure of upgrading the AS5200 and it is identical to

upgrading a 2500:

3000, AS5100, and AS5200

Here is a documentation on how much flash memory the 5200 will support,

16 megs is the max:

If I understand you correctly you were asking which mode you need to be

in to load the IOS into flash, you will need to be in bootmode to copy the image into flash. Please let me know if this is the information you were seeking. Thank you.
