Re: JTAG emulator for MPC8548E (v2)

Hi Wolfgang,

The new unit works *mostly* fine. No debugging issue (not that I use it
that much anyway, now that the board boots Linux), but still a flash
programming issue. Programming the target parallel NOR flash works in
slow JTAG mode, but not in faster mode using the internal workspace. I
reported the problem

This may as well be a misconfiguration in your config file, like
setting wrong flash timings.

I agree with you there, but I haven't been able to find which setting I got 
wrong. I dumped the registers contents after the board gets initialised by 
U-Boot, and all related values are identical. I even traced the U-Boot code 
and tried to reproduce the exact initialisation sequence, without luck.

This is definitely an initialisation issue, as programming in workspace mode 
works when the board gets initialised by U-Boot first (wrong reset vector 
setting in the config file, which makes the BDI freeze the processor after it 
started up).

several months ago and still haven't received any solution. It might not
be Abatron's fault, the French distributor might not have reported the
problem to them. Abatron people speak German only, and will not respond
to e-mails written in English (nor will they talk to you on the phone,
they just hang up).

I cannot confirm this. On contrary. Abatron's support is one  of  the
best  I've  ever  seen,  and I have seen a few. And of course you can
send messages in  English  to  support@abatron.ch,  and  you  do  get
replies.  And  they  do  answer  the phone (in German and in English,
too).

I might have been unlucky, but the person who picked the phone definitely hung 
up on us when he/she realized we were speaking English.

The BDI-2000 is a nice product, but has a few bugs, is IMHO overprized
and has one of the worst support service I've had to deal with.

Hm... we have about 15 such devices in daily use. I don't doubt  your
report, but you must have had really bad luck. This is NOT the normal
situation with Abatron or the BDI.

Glad to hear :-) I will try again then. Thanks.

Best regards,
