First of all, I am new in this field, I am trying to boot linux on Beagle Board Rev. C3 with no success. Steps I took for booting is taken from this wiki https://eewiki.net/display/linuxonarm/BeagleBoard . It is created by Robert Nelson. I can see that U-Boot is started and trying to start Linux kernel, but as control is passed to kernel I stop getting output. It looked like low-level debug is not configured for OMAP3. I tried to recompile and configure kernel. In menuconfig I select Kernel hacking ---> Kernel low-level debugging functions ---> Kernel low-level debugging port and I select "Kernel low-level debugging messages via OMAP3 UART3". I also select Early printk(I am not sure if I need this). After compiling I have no progress. I also connect monitor via hdmi and I see yellow screen only.
Could you please give me some idea? This is my output: U-Boot 2016.09-dirty (Nov 02 2016 - 12:23:39 +0100) OMAP3530-GP ES3.0, CPU-OPP2, L3-165MHz, Max CPU Clock 600 MHz OMAP3 Beagle board + LPDDR/NAND I2C: ready DRAM: 256 MiB NAND: 256 MiB MMC: OMAP SD/MMC: 0 *** Warning - bad CRC, using default environment Beagle Rev C1/C2/C3 Timed out in wait_for_event: status=1000 Check if pads/pull-ups of bus are properly configured No EEPROM on expansion board Timed out in wait_for_bb: status=1000 No EEPROM on expansion board OMAP die ID: 3d00000300000000040323090b01e00a Net: usb_ether Error: usb_ether address not set.
