debug using hyperterminal

[firefox1965]

hi
has anyone got a tutorial on how to debug using hyperterminal and a null modem cable only?? box wont communicate through the ethernet port and this is my last option.

You have to enable the virtuell debug and transfer ppcboot via the nullmodem cable to the box.
Valid and usefull only for a nokia 2xintel BMon1.0 with faulty network device.

First setup Hyperterminal for a direct connection via com1
and the comport settings:
Bits per second - 9600
Data bits - 8
Parity - None
Stop bits - 1
Flow control - Xon/Xoff

Next you need control over the bootloader.
Start the box and press the up arrow button until you get the numbers and do the flashreset as described in the debug enable tuts.

Type in Hyperterminal

icache [press enter]
icache is on

If you get the response "icache is on" the flashreset was ok.
Disconnect the flashreset line.

Type in Hyperterminal

dl [enter]
S Record Load, offset: 0

S208029c600000000000 [enter]

dl: srec chksum error in line 1.
in record 0x0, calculated 0x...
dbox2:root>

If you get dbox2:root> you have control over the bootloader.

Type

dl 800000 [enter].
S Record Load, offset: 800000

Transfer ppcboot.mot via Hyperterminal and text file send to the box.
After around 10 minutes you get the message
DL: start address 0x800000
dbox2:root>

Type

chorus 800000 [enter]

Follow from that point on the debug enable tut for nokia 2xintel BMon1.0.

Thats only the log from booting.
You have to interrupt the startup with the up arrow button to get the prompt from the bootloader.

I did get it sorted, working a treat now - thanks to all those who made this possible.

I was going to scrap the box and buy a new one that was already in dubug mode. By investing a bit of time on this forum, i have managed to save my self a few bob!!!

Thank you all for all your help and effort.
