Does the E2 have a Smart *Card* socket or a Smart *Media* socket? I can't seem to find a definitive spec.
And does the E2 have a Pocket Docket, or was that only the E1?
Yes yes yes - has a smartcard socket, a smartmedia socket (BTW, where the hell can I buy one of these ancient things from these days?) and a pocket docket thingy. (4-pin serial nastiness - probably vcc/gnd and txd rxd - wouldn't be surprised if it was usual UART RS232-style data format (but at 'TTL' levels probably)).
I was hoping to avoid all that messy JTAG stuff, but it's obviously the way to go.
The company I work for does embedded operating systems, and
*rummage around in drawers*
it took me 15 seconds to lay my hands on an Insight IJC2 parallel port JTAG adaptor from some long-defunct piece of hardware, but unfortunately my home computer doesn't have a parallel port. Plus, it would appear that I'd need to solder pins onto the E2's motherboard to make it work.
Yeah :( It's pretty easy though, it's brought out to some pads on the board.
Can anyone reccomend any Linux JTAG software? Are there any standard interfaces?
:( Here's where it got annoying for me. If you have an OCD 'wiggler' parallel port cable, then you're in luck (me neither..) because OCD Commander is available free (Windows + Linux, nicely), plus IMHO the more useful GDB-stub-to-JTAG. (http://www.macraigor.com/ocd_cmd.htm) This will drive ARM's EmbeddedICE via JTAG and looks pretty cool. I couldn't find anything as polished, free, for my JTAG cable under linux. I ended up using libjtag + armtool, which works with a variety of parallel port cables.
If you do wire up a cable compatible with Macraigor's cable (the schematic of the wiggler is around on the net in various places), that looks like a good bit of software. I'm using Xilinx's JTAG cable - it'd be easily modified to use the wiggler pinouts, but I don't want to sacrifice it cos I still use it for its original purpose.
As for the PBL ROM image, I'll drop in to Dixons this evening and get an E2 --- then I'll have a genuine license and you can send it to me quite legally, muhahaha.
Ahh right ;)
Cheers,
Matt
