Asking about LM3S811 Arm Cortex-M3 Evaluation Kit

[BravoV]

A friend of mine just sent me this ARM cortex-m3 evaluation kit to play with, and it came with only the jtag cable and nothing else. Though he said originally it was bundled with a program CD and an USB cable, but he lost them. 

I've spent my time at TI website downloading & reading lots of this cpu, eval kit and it's supporting documentations, and when it comes to the physical appearance, the current evaluation kit has some differences and I can not find the revision documentation on this eval kit.

Are they the same thing ?

Took a shot of my board (top pic) and the one from the eval kit documentation downloaded from TI, put those purple arrows show those differences.

Hi,

The top board was manufactured for Luminary Micro (probably before the acquisition by TI). The current board at TI website is Rev B, therefore I imagine this one is Rev A.

Functionally I think the two boards are identical, but the schematics may have changed a bit.

All in all, I found a user's manual for Rev A at the page below:

Rafael, thank you so much, that is exactly what I was looking for, great finding.

Looks like TI dumped all old Luminary Micro's documentations after the acquisition.

I have the ethernet series version of this kit so I'm assuming this is similar:

The debug/JTAG is all done through USB and the JTAG header is for one of two things: You can use the USB JTAG interface for a different external board (hey free JTAG programmer!) or you can use your own external JTAG device.

And yes, TI bought out Luminary micro and rebranded everything. You'll find a lot of the schematics, diagrams, and photos on the TI site still have the luminary micro logo on them!

metalphreak, thanks, didn't know that it can be used as jtag programmer too, cool.

BravoV,

I tried to find this "Rev A" manual at TI website with no luck.

However, I found something else that may help you in the future. The forum thread below will help if you intend to use the OLED display someday.

Yep See page 18 of this: http://www.ti.com/lit/ug/spmu030b/spmu030b.pdf


Also found this:

Revision Date Description
0 Aug 2, 06 Release for Rev 0 PCB
A Aug 18, 06 Release for Rev A PCB, First Production Release
B Feb 2, 07 Add 5V break-out pad.
C Jul 17, 09 New RIT display, supports Serial Wire Out (SWO)

Looks like the only major change is to a different OLED lcd. StellarisWare package should have the 'driver' for both.

Seeing as how your board has no 5V pad (bottom left) I would say its a Rev A.

@Rafael, thanks again, that information will keep me from scratching my head if that happened.

I'm totally noob when it comes to this arm mcu platform, only done few simple atmel avr 8 bit projects, it was a chit-chat with friend on 8 bit mcu, then suddenly he said "real man use Arm mcu, here something to play with" and here I am. 

@metalphreak, where did you get that list from ? And thanks, yeah, just realized and spotted the jtag programmer feature. <thumb up>

It's in the bottom right corner of one of the schematics in the datasheet/PDF

(page 28 in the link in my last post. "bottom left" if you rotate it the right way)
