My Tizen test device(Tizen RD_PQ)
have a problem:
 
When i press the power button, 
first it show a TIZEN logo, and then it show 6 rows message:
 
Dump mode is
dump_panic-RSTST:0x20000000
RAM will be save on UMS or uploaded to
HOST
[LOG EXTRACT]
error:invalid getlog magic
Dump end with
ERROR
Ram Dump eXtractor v5.4
 
Then,the device  stays in this
state.
I tried download a firmware to the device,but the download process
fail again.
 
Now I need to use this device to
test my tizen app, So i want your help very much.
Could you help me to solve
the problem?
 
Thank you very much!
Good
regards!
