Stuck at "Starting Kernel..."

Hey, 

 

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

Here is my setup: 

 

 

This is the output i get, has anyone an idea what could be my problem or how i could debug the problem?

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) 

 

However linux is still not really booting correctly :(

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.

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.

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

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.
