Hi Will, The key environment variables are: bootcmd=tftpboot 0x30000000 bootimg.elf && bootelf gatewayip=192.168.168.1 ipaddr=192.168.168.2 serverip=192.168.168.1 The tftpboot command reports the IP addresses used so that you can check that they are correct. You might consider using tcpdump or wireshark to diagnose the problem. - Alex ________________________________________ From: Devel [devel-bounces@sel4.systems] on behalf of Will Korteland [will.korteland@gmail.com] Sent: Sunday, 14 December 2014 18:26 To: devel@sel4.systems Subject: [seL4] i.MX6 quad booting problems Hi everyone, I hope I'm using the correct list for this type of thing... I've bought my own Sabre Lite (identical to the AOS boards), and I've been trying for a few days now to get it to boot from tftp. I've downloaded the prebuilt u-boot.bin from the Sabre Lite hardware page, but it still doesn't seem to be working - it keeps timing out when trying to do the transfer. I think my tftp server is set up correctly, since it is the same as it was during AOS last semester. Could someone please boot a Sabre Lite set up for TFTP, interrupt the default boot process, type "printenv" into the U-Boot prompt and paste the results? Sorry if this is the wrong place to ask. Thanks, - Will ________________________________ The information in this e-mail may be confidential and subject to legal professional privilege and/or copyright.
