Two questions: 1. Where's a simple step-by-step document on installing the binaries I've built with Buildroot on to a AT91SAM9261-EK (or AT91SAM9(RL|XE)-EK, but the first is the target I really want)? I've tried using the Angstrom demo loader, just replacing the binary names in the TCL script, but that's apparently not it. 2. I've checked the "EABI" box on the compile, is that the prob...

Hi All, I have an ATMEL SAM7SE512 EK board. I am trying to port uClinux on it. But still unable to find the success. I have some porting experience with Linux kernel onto AT91SAM9263-EK board. I have read from portal regarding porting uClinux on to SAM7 series. In that portal he asked us to the existing support for ARM7TDMI controller(AT91x40). I found that portal was fine because my ARM core i...

I'm driving some hardware with the SAM9XE that has some hard real time limits: I need to lower some pins, wait for *two microseconds* then raise those pins. Any longer and I let the magic smoke out. Any shorter and the right thing fails to happen. I'm doing this on the AT91SAM9XE-EK with code that looks like: void Strobe( unsigned int bits ) { LowerPins(...); // an inline function...

Hi all, I'm a begginner in embedded debugging technologies. I'm sorry for my very basic questions.. I'm using AT91SAM9260-EK + Yagarto + Eclipse. I'm using Windows XP. I am trying to communicate with the card via USB. I have been reading about one week however I still have no idea how to do that. I don't know what to do with 6124.inf or usbser.sys files. Should I go through CDC or HID? ...
