Dear All, After erasing the data flash, NAnd flash and installing the Bootstrap loader and U-Boot, the problem is solved. I have a U-Boot prompt using which I should be able to proceed further.
Before building the Linux kernel and file system, I want to experiment with prebuilt images of kernel & FS. I have got a) Linux image --> Linux-2.6.27-at91-exp.3-at91sam9g20ek.bin b) File system image --> genericfs.arm.nofpu.jffs2. How do I install these image into the evaluation kit? The website www.linux4sam.org gives instructions to load the linux-2.6.27.img and samp-ramdisk.gz images. Is it necessary for any conversion? Thanks & regards Sandeep Suresh ________________________________ From: "Xu, Hong" <hong...@atmel.com> To: sandeep.sur...@yahoo.co.in Cc: u-boot@lists.denx.de Sent: Tue, 24 August, 2010 6:23:46 PM Subject: Re: Non-experimental U-Boot compilation Hi, > Dear all, > I am using the AT91SAM9G20EK kit and want to port Linux on this.

After POR, 1 1 2 1 1 2 continuosly prints on the hyperterminal. I > read from AT91.com that this is the expected behavior for the demo version. Yes, this is the expected behaviour for the demo package. When you see this, it means you do not boot from the media where you burn your U-Boot into. > What is rge procedure to get the prompt ? Are there any separate configuration > settings? AT91SAM9G20EK are well supported by both mainline code and Atmel's current binary. ( u-boot 1.3.4, a little bit old) For detailed steps to run U-Boot/Linux on your board, still, goto http://www.linux4sam.org BR, Eric
