SAM-BA 2.12 + at91sam9g35-ek problem

Thu Jan 17, 2013 6:52 pm

I've got SAM-BA 2.12 on a Windows 7 box and a stock at91sam9g35-ek dev board. When I start the SAM-BA app I select the com port to communicate with the device, select at91sam9g35 as the device and start the app. However, when I try to Enable NandFlash I get a message "-E- Script error: can't detect known device". I have a terminal program watching the debug port and I get this..

I'm trying to follow these directions.

-I- -- NandFlash SAM-BA applet 2.12 --
-I- -- SAM9XX5-EK
-I- -- Compiled: Jun 27 2012 13:39:59 --
-I- INIT command
-I- Device Unknown
-I- End of applet (command : 0 --- status : 1)

Any ideas? This must be something simple.

Check the state of switch SW1 (1,4) as this will disconnect the NAND's Chip Enable line.

In order for it to run SAM-BA it can't boot from NAND, but if you want to work with the NAND you'll need it reconnected.

Return to “SAM-BA”
