gnuarm + JTAG?
What JTAG flash programmer and inline debugger should I buy to use with gnuarm on linux (fc4)? Reflashing is more important than debugging (I can always use gdbserver over a serial port). Preferably using USB or ethernet -- the Embest C3 seems to fit the bill, but I don't know if it can be made to work with gnuar... 9 Mar 2006 20:12

JTAG connection to Blackfin BF533
Hi, Does anyone have a schematic showing the hookup to a byteblaster or wiggler compatible JTAG adapter to the BF533? I am not sure what pullups or pulldowns to use on the individual JTAG signals. Also there are two different wiggler cables (14pin and 20pin) I have the 20pin cable from Olimex.com: ht... 8 Mar 2006 19:14

Sony ACX705AKM LCD users/ spec questions?
We are planning to use this LCD in an embedded project with a Gumstix processor and I am having more than a little trouble getting support from Sony. The 1st problem is knowing how to drive the LED backlight. The spec simply says 15mA current source, but it does not give any details about the forward drops ... 8 Mar 2006 16:36

Backup battery for AT91SAM9261
Looking at the data sheet for the AT91SAM9261, it says the back up supply voltage range is 1.08 to 1.32 volts with a current of 2.5 microAmps. This could be supplied by a watch battery except I have no idea how to regulate the voltage to this range without draining the battery from the regulator quiessent current.... 7 Mar 2006 02:58

2 MBytes/sec using HID
We want to use a Cypress FX2 to send 2 MBytes/sec data to a PC via usb. In order to avoid writing a PC driver I'm considering using HID interrupt transfers. Latency should be better than 100ms say. Can anyone see any problems with this? Thanks, Arthur Richards ... 6 Mar 2006 01:30

MSP430-EasyWeb3
Hi, I found that MSP430 EasyWeb3 is good one to start as web server to control i/o devices remotely. I am now trying to use Rowley Crosswork as IDE and MSP430-JTAG as progammer for this device and also uIP example from Rowley Crosswork as sample testing how about this, any one have experience on this, I ha... 1 Mar 2006 13:28

MMSP2 and JTAG
Hi, a couple of weeks ago i bought a handheld gaming console containing a MMSP2 SoC. I have been playing around a little with JTAG and thought it could be fun to learn more about dual core debugging, but i have encountered some strange behaviour. The MMSP2 chip contains 1x arm920 and 1x arm940 core, and the 92... 1 Mar 2006 05:29

Broadcom pinout..
Looking for any info about pinout of BCM6345 from Broadcom with embedded Linux, the board I have has a bunch of testpoints (suspect JTAG but it's not a standard layout) and a 4 pin connector which think might be a serial port (2x I/O, one GND and a 3.3V supply) which will allow me to watch the boot process. --... 28 Feb 2006 18:11

Nubie question: Programming ATMEL MEGA8
After looking over a lot of cool projects based on the ATMEL family of microcontroller, I just bought a bunch of ATMGAG8-16PI's. I bought these because I was under the impression these where very easy to play with: + On chip RC oscillator, no need for a crystal for simple stuff + Lots of I/O pins with dec... 1 Mar 2006 08:14
