2011-03-19 10:34:06     jtag console in linux kernel

when i use jtag console in linux kernel, stdin is not reliable

 

root:/> ev

 

root:/> [1

 

root:/> j[0mobs

jobs: not found

root:/> rlsc

bin   etc   init  mnt   root  sys   usr

~dev   home  lib   proc  sbin  tmp   var

root:/>

 

 

 

stdout is correct, and stdin is behave as it is, only display is not correct.

 

where is the wrong?

how exactly are you connecting ?  are you using the jtag-console script from the u-boot sources ?

 

what version of software (toolchain/kernel/etc...) are you using exactly ?

I'm using the jtag-console script from the u-boot sources

 

version of u-bot is 2010r1-rc2

 

toolchain is 2010r1-rc2

 

kerner is 2009r1.1-rc4

 

Is it because of my kernel is too old?

you need to use the same version of things.  the 2010R1 saw fixes for the jtag console.
