Hi folks, i just has started using xat91sam9263-ek dev. board 1 week ago. i have been using nxp's lpc2468 mcu for 2 years. So i'am new on sam9263. i use Keil compiler and ulink2 debuuger. i cant load the given sample programs (for keil) to mcu on the at91sam9263-ek board using ulink-2 debugger. i compile the file truly but i always have an error message about connection. if you have su...

Hi, i have an AT91FR40162s board.When i am searching on AT91 community about this processor there is very less information given as compare to AT91SAM series. First of all what is the difference between AT91FR40162S and AT91SAM series??????? And when i installed Keil to my laptop, In the folder path Keil\ARM\Boards\Atmel\ three folders are there 1. AT91SAM7A3 2. AT91SAM7S 3. EB40A T...

Hallo, Keil RL-ARM ( RTOS and TCP Stack ) provides a EMAC driver for AT91SAM7X microcontroller using AT91SAM7X-EK. I did take this EMAC driver and ported it to AT91SAM9260-EK ( almost the same thing despite different IO pins and so on ). The EMAC driver is being configured to use MII mode, PCLK is ~200Mhz and MCLK is ~100Mhz. The SAM9260-EK jumpers and resistors where changed in order to mak...

Have built 650 units using the AT91SAM7S256AU Rev A chip. Next build used Rev B chip Ocaisoinal problems are encountered with starting the processor from power up. The application is running under Keil RTX. No changes make to code between Rev A and Rev B build. Using the JTAG to investigate shows the processor to be hung initializing the RTX. The main function is called which calls the os_sys...
