Hello
As JunOS is based on FreeBSD I'm suspecting that there are folks here who know both, partly because this is a low-level (firmware) issue.
I have 2 EX4200's. 4200-1 & 4200-2 let's say. Each has 2 slices. When I bought ex4200-1 they said it had 15.x on it - it had 10.x instead on both slices. EX4200-2 came with 15.x which is what I needed for BGP route validation among other things.
The 1st sellor sent me a jinstall for 15.x so I used it on ex4200-1 slice2 and of course it didn't work as uboot has to be upgraded.
So the 1st sellor sent me jloader for 12.x and I tried it (2x) but it still won't boot from the new 15.x slice (disk0s1) as it says it can't find the kernal.
Instead I have to set currdev=disk0s1: and then boot & it will boot to the old slice with 10.x - but I need to get 15.x running.
1 - can I copy uboot from 4200-2 to 4200-1 ?
2 - is uboot on eeprom ? does this mean that the jloader upgrade writes to the eeprom ?
3 - what can be wrong with my jloader file ? so I need a later one ? seems like 12.x would have the newer uboot.
Thx
