Hi, In the AT91_SPI_ CSR[0] Reg. I set(AT91C_SPI_CSAAT & (0x0 << 3)). I'm expecting the chip select active after tranferred, but don't see it going high at...
There is a setting to keep the chip select active or not after transfer. Read over the register definitions in the datasheet. To: AT91SAM@yahoogroups.com From:...

HI Mark, thanks for the reply. I am using AT45DB011 SPI dataflash which is interfaced with AT91SAM9263. I have followed the steps as per SAMBA scripts. 1....
Hi all, I've been reading the AT91SAM9260 doku for sometime now, and waiting to receive the devkit for a hands-on start-up. All this time I've been asking...
This is common for the whole ARM family. Many registers work on a "write a 1 to enable" or "write a 1 to disable" basis. This way you get atomic operations...
The PIO of the AT91SAM family usually has 3 registers for its functions. if you set a bit in the 'outout enable register' (write-only) the corresponding pin...
Thanks for both answers, I didn't know that writing a "zero" has no effect :) These explanations helped a lot.. Mit freundlichem Gruß / Best regards Bekir...
Hi, Bekir, The answer is that they use an architecture for PIO that I find very nice. In addition to being able to write a register directly, you also have...
... You have a bit more reading to do. The Atmel ARM device peripherals generally don't have registers that you directly read/write. Instead they have...
Narasimha, There are a couple of things that could be wrong. First, please note that SAMBA-Boot is NOT looking for raw binary data in the dataflash. It is...
Mark, I am not using dataflash card. It is 8-pin SOIC. The same SPI dataflash you can see in at91sam9261-ek board. After programming the dataflash using SAMBA...

Narasimha, Whether you are using a chip on the board or an external dataflash, the issue is the same. You cannot just blast your application into the memory,...

The problem with a loopback device is that you have to manually set the size parameters (disk size, sector size, etc) which is soooo easy to mess up. I figured...
