Hi Pushpa, Did you manage to get any progress? i guess you do an 'rx' command before you just 'program' (you just didn't write that ;-)) Do you have any way to see the code running on your board ? maybe a JTAG (e.g. MultiICE from ARM) that's the best way to see where things stand before you have output on your console. another way is to light leds. see the little booklet you got with the board. they show that code there. start with <linux directory>/arch/armnommu/kernel/head-armv.S, see at least that the code is loaded ok. good luck, ilan. -----Original Message----- From: dtpushpa [mailto:dtpushpa@indiatimes.com] Sent: Fri 16 August 2002 8:58 To: Ilan Pollak Subject: Hi, According to my understanding you're able to execute the image on Eval board AT91.Please help me in this part to execute my image on the real board. I am a newbie too in the linux world.And porting the uclinux from past 3 months :-( I used the olduclibc. I am porting uClinux 2.4.x, to an AT91 on ATMEL EB40LS board, using the latest arm-elf-tools(arm-elf-tools-20011219.tar.gz) and uClinux distribution snap(uClinux-dist-20020701.tar). And also using genromfs-0.5.1.tar. I used DRAM_BASE @ 0x02000000 and FLASH_MEM_BASE @ 0x03000000 they both have size of 0x00200000 on my board. the TEXTADDR was set to 0x02010000. With this new mem map I was able to run the image in the ARMulator. See the attachement. The real problem is, If I upload the "image.bin" using the windows Nt Hyperterminal(typing 'program' command),it just uploads the image and when i type 'go' command nothing happens means no console no error. NOTE: I was succesfully able to run 2.0.38 version(from CD) on the same Hyperterminal. Please Help me.

And also using genromfs-0.5.1.tar. I was successfuly able to run the image on the ARMulator. By using the Memory map of DRAM_BASE 0x01000000 and DRAM_SIZE 0x00400000. I uploaded the same image on my AT91 Evaluation board. After loading the same if I gave go! then nothing happens. Don't know why? The SW1 is in the uppermem position. I guess above number for DRAM_BASE and the default TEXTADDR (used for armulator) would not work and need to be changed for eb40ls board. Did you make any changes with this respect. Are there any other changes you suggest? Did you use CONFIG_SWAP_PORTS for console? Please help me to solve the problem. Note: I am using the hyperterminal on windows NT to load the image.

I'm (still) porting uClinux 2.4.17 into the EB40-LS (Atmel AT91, plus uCnet card) Does anyone knows where can I get specs of the uCnet card? I have uClinux prompt but I have no Ethernet. I get: cs89x0: Tx buffer not free! NETDEV WATCHDOG: eth0: transmit timed out eth0: transmit timed out, IRQ conflict ?? I try to debug, but I don't know which interrupt I should connect to. any known cures, documents, info etc.? thanks, ilan.
