I'm using the EBI to communicate with the FPGA. At some point I decided to test it with MMU disabled, and then FPGA didn't work any more. Reading is OK, but writing has one spurious WR signal. prog: // FPGA registers (only one shown) typedef struct { volatile DWORD a0; } REG_EBI, *pREG_EBI; // put REG_EBI on CS6 address #define REG_BASE (AT91_CAST(pREG_EBI) AT91C_EBI_CS6) //...

Hi from new member, with VCC risetime question for the SAM7S

On the AT91SAM7S, can the VCC risetime be slower than that of Vcore? The data sheet implies this, but does not actually state it. I'm...

On the AT91SAM7S, can the VCC risetime be slower than that of Vcore? The data sheet implies this, but does not actually state it. I'm fighting a problem that appears once in a great while, where it appears that the CPU fails to boot. We've identified VCC rise as an issue, TST tied to GND with 1k (changing that to 0 ohms ASAP). ------------------------------------

Hi guys, please help me out here. I have searched up and down and, for the life of me, can't find anyway to run SAM-BA under Win 7 64bit. From all I've read, I should be able to select "COM1", which is the port the Window's CDC driver is assign to my SAM7S256-EK board when I connect it, select the board from the list provided and be able to reflash it. However, I am getting the msg "F...

Hello there! I've been working on my new AT91SAM7S-EK and the USART0. I'm following the AT91SAM7S256 Serial Communications tutorial from James P. Lynch and i've had some problems to make it work. To connect my board with the computer and send/receive data, i used an USB/serial cable (pl2303) and the program "realterm". To see where was the problem i ran the next tests: 1.- Channel mode normal. ...

Hi there, I have no experience with SPI so I am coming across problems. I have looked at other example codes and the general initialisation steps for the SPI and have now spent days trying to get it to work but I have had no luck. Basically I have the AT91SAM7S-EK development board and I have put on a FM25CL64 NVRAM chip which I want to communicate to the board via SPI. Below is my Initiali...

Hi there, I've just started playing with ARMs, having just bought the AT91SAM7S-EK. I've done some simple LED flashing programs and hav got Chan's FatFS running on the board having soldered on a SD/MMC connector. However now I want to try and interface the ARM to another micro through a buffer chip so that I can use the ARM as a SD/MMC controler. I have looked at the datasheet and done so...

Hi dear friend, I'm working on linux2.6.30 kernel for At91sam9261-ek like board, in our board we have connected the irq pin of ads7846 to a gpio(PIN_PA22) instead of IRQ2(PIN_PC2), therefore we have encountered a problem in the kernel for activation of gpio interrupt instead of IRQ. My question is, How can I redirect the interrupt routine from IRQ to gpio? Also I have done the following m...
