I'm trying to figure out the reset behavior of my AT91SAM7XC256 : One of the features of our product is that the firmware can be upgraded. We have a firmware programmer routine that runs out of RAM and programs the flash from data received over a comms link. It all works fine if we cycle power at the end. But, if we try to reset the device programmatically, via: AT91C_BASE_RS...

Can anyone enumerate what the basic differences between a flash and ram based project are? Fundamentally why do some of the demo projects from the at91.com site work in the ram_debug configuration but not under the flash_debug configuration. I would have expected those demo projects to work correctly. Thanks, Tom

Hi list, hi Atmel fans, I am quite new to this list, as well as to ARM7. I spend the last years programming several controllers but mostly AVR from tiny15 to mega128. Currently I am developing some simpe USB device using an AT91SAM7256 for the first time. It is used as connector between USB and a proprietary RF data link. The basic program is already working fine. Now the last issue that I...

I have seen some info scattered through the atmel documentation that indicates that methods exist to program the AT91SAM7 range of micros in-situ. The documentation hints that the serial debug port can be used for in-situ programming, but that the Fast Flash Programming

Hello, I am using the ThreadX OS and tring to get it to work with the AT91SAM7S-EK eval kit and IAR Embeded Workbench. Much of last week was conversing with IAR and Expresslogic in tryting to get a file compiled and run in the flash of the AT91SAM7S. We have that going, however ThreadX requires Timer0 of the TC to run and cause an interrupt. If ti

Good evening, everyone, I'm trying to bring up a custom board with an at91sam9g45; the stock Linux image shows me debugging output as the kernel comes up (and then a kernel panic as the hx170dec driver does something nasty). I have tried building my own linux image using the at91sam9g45ekes_defconfig. Now I've verified that CONFIG_AT91_EARLY_DBG is set to 'y' but when I flash this ke...

Group, I've done two projects now with the SAM7S family of parts and in general I'm pretty happy with the part. My next endeavor is a fairly simple industrial control application requiring ethernet connectivity. I naturally assumed I'd use the SAM7X, but just about the time I started looking into this Freescale announced their new series of Coldfire parts internal FLASH parts wit...

I have been thinking of designing an AT91SAM9261 based board, it will have NAND flash as storage and SDRAM as memory. It will also have an lcd and will be running linux. Im only a hobbyist so and im not sure if i can do the BGA reflowing, practice makes perfect. Anyways, my first question is that would i be able to run an 4.2" 420x272 TFT LCD without too much of performance hit? Second, ...

hi all, We have used in a couple of month a self programming software for updating our software in the field. We are using the AT91sam7s256 device. The programming part is working verry well. But now we try to use it under the ucos_ii os. We have some strange probleme. As soon as we unlock a page, the ucos_ii stop working. I have 2 program, both of them have ucos_ii. 1 is the DLM and the ot...

I am using YAGARTO Tool to compile my project based on AT91SAM7X512. I have developed one project without RTOS. Its code size become higher than 265K and ram size around 64K. It works Ok. Now, i want to add TCP/IP. So, that i first make working webserver on my hardware. The TCP/IP Stack which i have used is for AT91SAM7X256. So, i modified every where with AT91SAM7X512 header file with its flash a...

Hello, After running my code in RAM debugger for nearly 6 hours it hung. I hit stop and it was stuck on the undefined instruction 0x04 infinite loop. Is this normal? What should it do to keep functioning and not hang? I am trying to find out why after a couple of minutes of running in Flash without the debugger attached to process stops, ie. my leds sto

Hello, I am making a system that has a segment of code that is static, does not change, to be a bootloader. Then I am flashing on the fly from ramfunc's a higher segment for some application data that can change. Now the problem is I am testing the system with flashing in garbage, and then doing a reset. Upon resetting a CRC of the image segment is done

Hi to everyone, 1)I am working with the ARM board mentioned above. I have crosscompiled a kernel and now I want to flash the board with SAMBA. So I connected the board over the RS232 and the USB_D interface to my host system (Ubuntu) powerd up the board and start SAMBA. I choose the USB0 for interface and now appears the fist problem. - Only the board AT91SAM9260 EK is available When ...

Dear list members, Recently I bought a Lego Mindstorms NXT kit, that uses an ARM 7 from Atmel (and a BlueCore board). It has an USB connection and it is able to program them by Windows tools; in e.g. the RobotC environment and the NXT-G environment of Lego itself. However, there are no flash programmers available for Linux for this specific NXT brick. So, I want to ask you, is there a...
