Stuck at "Starting Kernel..."

[Altera_Forum]

Hey, 

 I am trying to get a modified version of the GHRD-HPS running on my Arrow sockit board. Here is my setup: 

• Arrow Sockit Board with Cyclone V  
• Ubuntu Core (https://rocketboards.org/foswiki/view/documentation/ubuntucoreforsocfpgaarrowsockit) 
• The .rbf file seems to be read correct  
• I created and changed all the necessary files (preloader, uboot,...)  

  This is the output i get, has anyone an idea what could be my problem or how i could debug the problem?  U-Boot SPL 2013.01.01 (May 04 2016 - 00:41:22) BOARD : Altera SOCFPGA Cyclone V Board CLOCK: EOSC1 clock 25000 KHz CLOCK: EOSC2 clock 25000 KHz CLOCK: F2S_SDR_REF clock 0 KHz CLOCK: F2S_PER_REF clock 0 KHz CLOCK: MPU clock 800 MHz CLOCK: DDR clock 400 MHz CLOCK: UART clock 100000 KHz CLOCK: MMC clock 50000 KHz CLOCK: QSPI clock 400000 KHz RESET: COLD INFO : Watchdog enabled SDRAM: Initializing MMR registers SDRAM: Calibrating PHY SEQ.C: Preparing to start memory calibration SEQ.C: CALIBRATION PASSED SDRAM: 1024 MiB ALTERA DWMMC: 0 reading u-boot.img reading u-boot.img U-Boot 2013.01.01 (May 03 2016 - 18:49:51) CPU : Altera SOCFPGA Platform BOARD : Altera SOCFPGA Cyclone V Board I2C: ready DRAM: 1 GiB MMC: ALTERA DWMMC: 0 *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial Skipped ethaddr assignment due to invalid EMAC address in EEPROM Net: mii0 Warning: failed to set MAC address Hit any key to stop autoboot: 0 reading u-boot.scr 254 bytes read in 3 ms (82 KiB/s)# # Executing script at 02000000 reading output_files/RGBPatternGen.rbf 2762608 bytes read in 133 ms (19.8 MiB/s)# # Starting application at 0x3FF79544 ...# # Application terminated, rc = 0x0 reading zImage 3465776 bytes read in 161 ms (20.5 MiB/s) reading PatternGenSystem.dtb 23293 bytes read in 7 ms (3.2 MiB/s)# # Flattened Device Tree blob at 00000100 Booting using the fdt blob at 0x00000100 Loading Device Tree to 03ff7000, end 03fffafc ...

I managed to get a bit further by changing the order of the sopc2dts --board options ( first hps_common_board_info.xml and then the sockit info)

I had exactly the same problem a few weeks ago, apparently the provided .xml contained errors. 

Look in hps_common_board_info.xml and replace all DTappend by DTAppend In soc_system_board_info.xml, remove the > at line 22.  Personally I created the .dtb with sopc2dts in command lines with cygdrive env.

[Altera_Forum]

Thanks for the tip, however the DTappend was already correct for my version. 

Could you tell me in which order you passed the .xml files to sopc2dts? I am not sure if i am doing it correct.

[Altera_Forum]

I follow the tutorial at : https://rocketboards.org/foswiki/view/documentation/gsrd140devicetreegenerator 

Under cygwin environment :   $ sopc2dts --input soc_system.sopcinfo  --output socfpga.dtb  --type dtb  --board soc_system_board_info.xml  --board hps_common_board_info.xml  --bridge-removal all  --clocks

I ran into a similar problem and I ended up taking the angstrom-socfpga (Yocto) release, built the entire image and then started tinkering with the device tree. I never had much luck in porting the Qsys tree to DTB, especially with custom logic attached to the HPS. For me taking the home-build standard using cyclone5-defconfig, or something like that, and modify it to fit your new design works best. I remember having problems with Watchdog timers that where put in the device tree by the sopc2dts tool but were actually lacking in h/w causing trace dumps just like yours.
