I got my Stellaris several weeks ago.

You power the chip like normal from its own supply.

I was looking at playing around with the ARM Cortex family of microcontrollers, but I'm not sure of what tool chain and programmer to use. I already have several evaluation boards, but I need to be able to implement the chip on my own PCB and program it via JTAG/SW. Does anyone have any advice on where to get started?

I should have said I'm not new to embedded programming. I've been using Atmel microcontrollers up until now with Atmel Studio and programming them with a JTAG cable. I've played around with TI's Code Composer Studio with their Stellaris Cortex-M4 eval board but have not read anything about their ability to program external chips. I just now found that NXP's LPCXpresso can be used to program their own chips which is pretty much what I was looking for. I read that ST has their own programmer device, but the software support for it seems to be deficient. I will probably just go the LPCXpresso route.

I said I have been using Atmel microcontrollers. movax posted:If you can get away with it, using a simpler 8-bit/16-bit micro (tinyAVR, PIC, MSP430, etc) I have been and want to move up to something more powerful. evensevenone posted:You can use the ST-Link with this: https://github.com/texane/stlink and just use gdb. I didn't know that. I have a Discovery board that I haven't touched yet, so that would be useful.

Has anyone used NXP Cortex M0/3/4 chips, and their LPCOpen library?

Nevermind, I was having trouble getting SPI to work on their LPC1316 Cortex M3, but their support got back to me. It turns out when setting the IO mode of a pin, the value of reserved bits is important. You can't just set the lower bits to what mode you want and set the rest to zero if there are reserved bits that default to 1.
