That is because you have not enabled those EARLY PRINK or DEBUG LL. Similar thing is needed for N900 and IIRC in some of my linux-n900 branches I have config for it. Plus it needs patching some arch/arm source files to make it working. > But I'm _still_ not getting any output on decompressor... early > printing works ok on "S" but not on "P". I guess there can be either problem with memory mapping and RAM size or with OMAP HS mode? -- Pali Rohár pali.rohar@gmail.com
