I've found this datasheet too. But it is useless since its really hard to track JTAG pins, so we still cant use them. Only 100% solution to this - x-raying PCB. And I still unsure about chip package - CPU I've found inside my n2g is 9x9mm, while S5L87 is 10x10mm.
Here is something I've found today: http://imtl.skku.ac.kr/imtl/Course2008/NS/final/paper/Surveyonthepractical.pdf Its paper about JTAG protection for application processors, code encryption, boot ROM and some other things you probably heard of. And two of three of its authors have their mail @ samsung.com. So I think debugging won't be as easy as it seemed. 2009/3/26 <[email protected]> > > > http://rapidshare.com/files/101234522/S5L8700X-DS.pdf.html > > > > While searching around, I came across a link to the S5L8700 datasheet on > the Rockbox wiki.
