Hi All, I am working on at91sam9261ek and I want to make PCK0 work on PB2. I configured PB2 as periph B and set SCDR, PCKR(0) and SCER. I built the kernel and loaded it to the board. But when I measured PB2, there was no square wave on scope. The following is part of the retail messages: entering my driver scsr = 0x10041 scsr = 0x10141 sr = 0x10f Advanced Linux Sound Archite...

Hi everyone! I would like to use a SerialFlash (AT25/AT26) for my bootsrap as well as for u-boot storage. The SAM-BA applets are able to identify, enable and erase the flash I'm using now (M25P16-VMP6G). Even sending of the bootstrap works - meaning it is executed after reset and therefore obviously transferred in some way. But while transferring any data, the SAM-BA freezes and has to be...

After the deviceState becomes "USBD_STATE_DEFAULT" and USBDCallbacks_Reset() is called, the deviceState goes back to 0, which is suspend, and...

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). ------------------------------------
