Hi, I am evaluation IAR 5.2 and IAR 5.3 products. Both seems to fails to program the on chip FLASH of sam7s256 and sam7s64 chips. Version 5.2 hangs after a progress bar window pops up saying "Programming flash". Version 5.3 reports an error in the debug log (similar to "Flash programming failed."). The same boards work fine with IAR 4.41. Does anybody has a solution to this problem? ...

Hello, I working on project that is based on FreeRTOS for AT91SAM7X256 (Crossworks compiler). I would like to implement following functionality. Let?s assume that because of some system conditions (e.g. number of watchdog system restarts) I would like to decide if software should start FreeRTOS kernel or not. If not it would start typical while(1) loop and work without FreeRTOS but

Hi Fellas, I am working on a project and no JTAG debugger is available for me. The current approach I'm using is simply printing variables to DBGU port and frustrating trial/error process. There are three wires connecting to my device now ( beside supply voltage) that are capable of data transfer : DBGU (Currently Debugging), USB (ISP and Data) and Ethernet (Data) interfaces which are all fu...

Hello, I need to develop embedded system with ethernet communication capabilities and we need to use TCP for the communications between the Embedded system and the Application on the Windows PC which we are developing, i am using ATMEL AT91SAM9260ek board, since our development costs are low i am looking for a free TCP stack to use in my project, I looked for free TCP stacks but din find many...

Hi all, I got two questions: 1- Can DMA Controller perform data transfer from Tightly Coupled Memory? If yes, 2- Would it be faster than normal DMA transfer? Best, Bekir

hello all, I have made a customised version of AT91RM9200-EK_Rev_A01 board from atmel.I have davicom DM9161AE connected as PHY in RMII mode and pulse engineering pe1012 as pulse transformer. when I boot linux on this board, linux boots properly, it detects DM9161AE ( I have confirmed it by disconnecting 50MHz clock to 9161AE and then it gives mesaage PHY not detected). But after booting it gives ...

I'm trying to use the AT91SAM9XE in SPI slave mode. Looking through the source to the Atmel supplied SPI code for the AT91SAM7S256 I'm having trouble figuring out how to convert some of the functions. Anyone got a suggestion for SAM9 SPI slave mode sample code? Thanks. Dan ------------------------------------

This should be easy (I think). I've turned on "Device Drivers---> SPI Support---> User mode SPI device driver support" in my kernel config (built in, not a module). In linux-2.6.28/arch/arm/mach-at91/board-sam9261ek.c, I added the following to the "spi_board_info ek_spi_devices" array: { /* comm to my sub device */ .modalias = "spidev", .chip_select = 1, .max_speed_hz = 10 * 1000 *
