Re: gEDA-user: OT: OpenOCD?

[John Doty <jpd@xxxxxxxxx>]

Thanks to all who replied. I am not too concerned about some gdb  
difficulties, as I make little use of gdb: it seems a miserably  
inefficient approach to debugging. I'm a trapper, not a hunter: unit  
tests, assertions, and logs are my main debugging tools. So OpenOCD  
looks like the tool for me.

Well, I've been using the Atmel EB40A board for several years for a  
variety of "one shot" embedded projects, so I've managed to penetrate  
much of the fog there. The ARM looks pretty familiar to an old System/ 
360 programmer ;-)

But the EB40A has the firmware to upload code over the serial line:  
I've not used JTAG for it (or anything else). Need a fancier chip  
(hardware SPI support) for the new project, and the eval board for  
that apparently needs JTAG.

Yeah, but I'm not an FPGA designer. I'd like to find an FPGA project  
where my application expertise is sufficiently overwhelming that  
somebody will put up with my FPGA learning curve. Not this one. The  
main tools for this one need to be gcc and a soldering iron, given  
the low budget and the short fuse.

Yep. Flown a bunch of them. I can write requirements for FPGA  
designers, just have never done the work. Used to be the foundry code  
on the package would tell you if an Actel part was rad hard, and  
distributers would sort that out for you for a little extra, but now  
you have to send big $$ to Actel to get the right stuff.

But my ARM project is ground-based in its current incarnation.
