[U-Boot-Users] Slight OT: Lauterbach vs bdi2000

[Umar Quershey]

Hello,

 

I am looking into purchasing a JTAG dongle for doing U-Boot/Linux
Porting + Linux Driver development (essentially all GNU stuff).  Would
anyone recommend Lauterbach over the bdi2000 or vice versa?  And why
would one pick one over another?

 

Regards,

Umar

Yes, of course. Lauterbach will recommend ... guess what?, and Abatron
will ... 

There are many sides to be considered, including  existing  equipment
and  experience.  When  you have a box from vendor XXX stting on your
desk you  should  probably  use  it.  When  you  have  ten  years  of
experience  using  the  tools from vendor YYY you should probably use
their tools again.

Having said this, I can say that DENX is using the BDI2000 exclusive-
ly, on ARM, PowerPC, MIPS, ColdFire, ... The bdiGDB  version  of  the
firmware  allows  for  an  excellent  integration  in any Linux based
development environment. The biggest advantage is that  you  can  use
the  very  same debug interface for U-Boot, Linux kernel and drivers,
and for application code (there is no difference if you attach GDB or
DDD or Insight or ... to the BDI2000 or to a gdbserver running on the
target). Also, Abatron technical support is the best I have  seen  so
far in the tools area.

Just my 0.02 EUR...

We have evaluated BDI2000 and used Lauterbach in the past.
Lauterbach is definitely the best choice for debugging many different 
target CPU running Linux and WinCE, but debugging environment is mainly 
targeted for Windows, and is too much expensive.

At the moment we use Ronetix' PEEDI debugger and support it with our 
products. PEEDI has almost the same features as BDI2000 but is faster 
and costs less, unfortunately does not support yet PowerPC and MIPS but
supports all ARM7, ARM9, XScale, based MCUs as well as AT91SAM7, 
LPC2000, MAC7100, STR7, STR9 and TMS470 families.
It give an excellent integration in any Linux based development 
environment too.
It is the only debugger I know that allow NAND Flash programming.
