Follow-ups

--- Sonic Zhang 2012-09-10 07:33:27

There are 2 issues in the new uClibc 0.9.33.2.

One is the vfork blackfin implementation is missing.

The other is the FDPIC dynamic library loader is not compatible with the FDPIC

dynamic library generated by Blackfin GNU toolchain.

--- Sonic Zhang 2012-09-21 02:29:25

Now FDPIC buildroot Linux image can boot up on bf609 with 2 patches attached.

Patch 1 shows where the FDPIC library loader crash occurs.

Patch 2 changes the type of var i from unsigned int to int. The following loop

is a decreasing loop, stop condition “i>=0” always meets in case of

unsigned int.

--- Stuart Henderson 2012-09-25 09:38:18

this should be fixed now.

--- Mingquan Pan 2012-10-08 06:09:39

Yes, it boots up now. Close.
