SAM-BA 2.9 and SAM9G45

pma · **Posted:** Sat Sep 12, 2009 8:19 am

I have a custom AT91SAM9G45 (-ES, date code 0924) board that I am trying to get SAM-BA working with, over AT91SAM-ICE.
I took the AT91SAM9G45-EK tcl scripts, and disabled everything except internal SRAM, peripherals, etc. I am using LPDDR SDRAM, so dealing with that will come later.
When I launch SAM-BA 2.9, select \jlink\ARM0 and the modified board, I get the following error dialog:
"No valid processor ID found"

Using Segger's J-Link Commander:

Code:

So the Mfg ID is 0x1f (Atmel), and the Part Number is 0x7926. This does not match with the latest 9G45 datasheet (should be 0x5B27).
Any idea what might be happening here?

You should open JP10 First,and you can also try using USB to connect the borad.

I have ES2 board with 0942 code and it doesn't communicate via USB even with opened JP10. Via Serial communication I have a same Problem with "No valid processor ID found"

@ pma: If you realy have ES board try to use an algorithm described in Errata for this MCU:

In my case it doesn't work. Probably because I have ES2 and this errata is for ES.

Good luck and write here how you can resolve your problem

There is an MBS-SAM9G45 Evaluation Kit which is also based on Atmel AT91SAM9G45 processor, it has followings features:
1) Composed of an SAM9G45 ARM9 Core Board and a full-featured Base Board which has plenty of peripherals and connectors.
2) With three kinds of TFT LCD Panel with touchscreen: 4.3", 7" and 10.2"
3) Pre-installed Linux2.6.30 OS on it, and is provided with BSPs for Linux2.6.30 and WinCE6.0 OS.

For more information about it, please refer to: http://www.samicc.com/2010/0807/mbs-sam9g45.html
