[panda-users] replay records with PANDROID

Mon Jul 11 08:06:16 EDT 2016

Hi,

It looks like you are missing the "-android" option when replaying line2.

Also, if you are using the most recent git version of PANDA, note that
a recent change introduced a regression to the ARM record/replay
support. If you roll back to commit 38e9caf ARM record/replay will
work correctly. This issue is currently being tracked at
https://github.com/moyix/panda/issues/91 and we'll try to get it fixed
soon.
