Hi Jon, David and others,

I am working on FIS for Microblaze CPU. I would like to use it. I have one problem.

I download latest DTC version from Jon git server.

Version: DTC 1.1.0-g1577696b

I tryied to convert DTS to DTB for Microblaze CPU. (DTS is below) #dtc -f -O dtb -b 0 -V 16 system.dts DTC: dts->dtb on file "system.dts" system.dts:27 syntax error FATAL ERROR: Couldn't read input tree

I got this error - I don't understand what is wrong. Older DTC version has no problem with it. This part is no problem - I can use older version of DTC(Version: DTC 1.1.0-g2512a7eb-dirty ).

The second things is around mkimage utility. I want to generate ITB file from ITS description. Latest DTC compiler has problem with it too.

Can you tell me which version are you using? I tryied to complile ITS to ITB with older DTC version and this version don't know about data label in kernel specification. I had no problem to add (for FDT + kernel version) DTB file but kernel file is not loaded. Is label data = "/incbin/("./linux.bin")"; OK? linux bin is in the same dirctore where is microblaze.its file.

Latest DTC has problem with ITS too $ mkimage -f microblaze.its microblaze.itb FIT format handling Trying to execute "dtc -I dts -O dtb -p 500 microblaze.its > microblaze.itb.tmp" DTC: dts->dtb on file "microblaze.its" microblaze.its:5 syntax error FATAL ERROR: Couldn't read input tree mkimage: Can't read microblaze.itb.tmp: Invalid argument $ dtc -v Version: DTC 1.1.0-g1577696b [monstr@monstr linux-eu-2.6.24]$
