We have an Atmel EB55 board (ARM7TDMI in AT91M55800A chip) and the AT91 expansion memory card. When have debugged projects on it using an Abatron BDI2000 successfully, but now have to (customer requirement) use a Multi-ice. The multi-ice works fine with the EB55 board, but we can not successfully download code to it if the memory board is plugged in. We have checked the setup again ...

Hi there, We are porting a windows application from desktop into embedded Linux on Atmel AT91 ARM Cores, thus we need JTAG to debug the firmware under a Linux environment. However, SAM-ICE only connects via USB to a PC running Microsoft Windows2000 or XP. So I am looking for a JTAG emulator running on Linux. If you have any good idea/knowledge, could you please help? BTW, a frien...

Does anybody know if either the MSP430 or Atmel ATmega AVR parts (or associated JTAG interface widgets/SW) have problems when there are other devices in the JTAG chain? In the past, I've run into buggy JTAG stuff that couldn't tolerate having multiple devices in the JTAG chain. I'm working on a design with both an AVR and an MSP430, and I'd like to have a single JTAG header/chain. Before...

Part data sheet and CAN bootloader documentation recommend "releasing" PSEN before the end of RESET when using PSEN=0 as the "hardware condition" forcing the on chip CAN bootloader to execute. The Atmel Demo board just has a DIP switch to ground to force PSEN=0; it doesn't "release". Even though the Demo board doesn't use PSEN as an output, shorting this pin to ground must not be a g...

I've got a Atmel 8051 (T89C51RD2) with 64K flash. Can I use part of the program flash for data storage? From the datasheet it seems like I should be able to use the on-chip low-level routines to program up to 128 bytes with the PROGRAM DATA PAGE call and read bytes with the MOVC opcode. I'm envisioning reading some data from flash into RAM, doing some processing and then writing it back t...

Hello-- I'm in the process of designing a new embedded system using the Atmel AP700x series of 32-bit embedded processors. There are currently three processors in this series: (1) AP7000, (2) AP7001, and (3) AP7002. Both the AP7000 and AP7001 have BGA packages and integrated LCD controllers. The AP7001 is packaged in a 208-LQFP, and does not include an integrated LCD controller. ...

Hello. I'm having a problem with a H8S MCU ( 2328) uart I use to comunicate witch a GSM module. First I was using a Atmel MCU instead of the H8S and all was working fine. But when I have replaced the Atmel with the H8S the communication dosen't works. I have seen thant the problem is that when the GSM module tries to respond to the H8s, the signal level ( H8S-Rx ) doesn't reach to zero ...

I am testing the sample project ADS7843_EXAMPLE1 with SAM3S-EK2 and Atmel Studio 6. I am using SAM-ICE (SEGGER) for debug via JTAG.

Atmel has a press release out for an ARM9 product line that includes on chip Flash. I have looked at their web site and I don't see anything about this other than the press release. At the bottom of the release they refer to the SAM9260 on their web site, but this part has no on chip Flash. Is this the 0 kB version of a family with Flash? Or are they no where near silicon on the part they...
