[U-Boot] Problem Booting RTEMS with u-boot on Phycore LPC3250
by SAeeD 17 Sep '12

17 Sep '12

Hello I have built an RTEMS 4.10.2 elf image for Phycore LPC3250. I am using u-boot as my bootloader. Although I can boot the image in binary format, unfortunately there is a problem to boot elf image with bootelf command. after executing bootelf command u-boot get stuck in an infinite loop with the following messages: Loading .start @ 0x80000000 (1120 bytes) Clearing .vector @ 0x80000000 (5952 bytes) Loading .text @ 0x80000460 (68576 bytes) Loading .rodata @ 0x80011040 (6208 bytes) Clearing .robarrier @ 0x800012880 (972672 bytes) Loading .data @ 0x80100000 (2016 bytes) Clearing .bss @ 0x801007e0 (5504 bytes) Clearing .work @ 0x80101d60( 66036384 bytes) I have tried both u-boot 1.3.3 and u-boot 2009.03 and have not found any improvements. RAM address info is located in range of 0x8000000 to 0x83ffffff; U-boot is located in 0x83fc0000. bootelf is called with argument 0x81000000. Any idea, hint, and advice on how to solve the problem would be appreciated. Thanks. SAeeD

[U-Boot] AR8031 Ethernet on mx6
by Fabio Estevam 17 Sep '12

17 Sep '12

Hi Jason, I don't have a mx6qarm2 and would like to ask you if you could please confirm that Ethernet is functional on mx6qarm2 running the latest U-boot. I am trying to get Ethernet working on mx6qsabresd, which also uses the same AR8031 PHY, but it is not working yet. AR8031 is supposed to output a 125MHz clock to mx6q, but I see a 25MHz clock instead. I do the same PHY init as in mx6qarm2. Any ideas/suggestions are appreciated. Thanks, Fabio Estevam

[U-Boot] Limit of kernel size
by J.Hwan Kim 16 Sep '12

16 Sep '12

Hi, everyone Is there limitation of the kernel size which u-boot loads? My kernel is very big, because I included the ramdisk into the kernel. My kernel size is over 40MB. When I load the kernel through u-boot, the prcedure hangs in the boot step. The step is "Uncompressing Linux.... done, booting the kernel" Thanks in advance. Best Regards, J.Hwan Kim
