Greetings,
I'm trying to get uboot 2017.7 working on my odroidc2 board. I have a image without uboot, I've compiled uboot with the correct defconfig. the image has two partitions, boot (fat32) and root (ext4), I've followed the howto in the readme file, generated and burnt the needed files into the image. I'm using teh vendor's kenrel (based on 3.14.79), my boot.cmd looks like this: setenv m "1080p60hz" # Progressive 60Hz setenv m_bpp "32" setenv hpd "true" setenv monitor_onoff "false" # true or false setenv nographics "0" setenv mesontimer "1" setenv disableuhs "false" setenv mmc_removable "true" setenv usbmulticam "false" setenv condev "console=ttyS0,115200n8" # on both setenv maxcpus "4" setenv max_freq "1536" # 1.536GHz
if test "${m}" = "custombuilt"; then setenv cmode "modeline=${modeline}"; fi
setenv bootargs "root=/dev/mmcblk0p2 rootwait ro ${condev} no_console_suspend hdmimode=${m} ${cmode} m_bpp=${m_bpp} vout=${vout} fsck.repair=yes net.ifnames=0 elevator=noop disablehpd=${hpd} max_freq=${max_freq} maxcpus=${maxcpus} monitor_onoff=${monitor_onoff} disableuhs=${disableuhs} mmc_removable=${mmc_removable} usbmulticam=${usbmulticam}"
setenv loadaddr "0x20000000" setenv dtb_loadaddr "0x01000000" setenv initrd_high "0xffffffff" setenv fdt_high "0xffffffff" setenv kernel_filename Image setenv fdt_filename meson64_odroidc2.dtb
fatload mmc 0:1 ${loadaddr} ${kernel_filename} fatload mmc 0:1 ${dtb_loadaddr} ${fdt_filename} fdt addr ${dtb_loadaddr}
if test "${mesontimer}" = "0"; then fdt rm /meson_timer; fdt rm /cpus/cpu@0/timer; fdt rm /cpus/cpu@1/timer; fdt rm /cpus/cpu@2/timer; fdt rm /cpus/cpu@3/timer; fi if test "${mesontimer}" = "1"; then fdt rm /timer; fi
if test "${nographics}" = "1"; then fdt rm /reserved-memory; fdt rm /aocec; fi if test "${nographics}" = "1"; then fdt rm /meson-fb; fdt rm /amhdmitx; fdt rm /picdec; fdt rm /ppmgr; fi if test "${nographics}" = "1"; then fdt rm /meson-vout; fdt rm /mesonstream; fdt rm /meson-fb; fi if test "${nographics}" = "1"; then fdt rm /deinterlace; fdt rm /codec_mm; fi
booti ${loadaddr} - ${dtb_loadaddr}
and this is what get: GXBB:BL1:08dafd:0a8993;FEAT:EDFC318C;POC:3;RCY:0;EMMC:800;NAND:81;SD:0;READ:0;CHK:0; TE: 436267 no sdio debug board detected

Starting kernel ...
the system stays stuck there.
any ideas how I can fix it? or even start debug it?
Thanks,
I was able to track the stuckness to armv8_switch_to_el2_m. how can I debug that macro? what can cause the code there to get stuck?
Thanks,
Dagg.
