Subject: Fix issue where "unknown chip id!" is seen every other time
X-Git-Url: https://git.gag.com/?a=commitdiff_plain;h=ff40ab6681591efa23d1068faae3417ff75d2393;p=fw%2Fstlink

Fix issue where "unknown chip id!" is seen every other time

Previously when running the program, reading the chip version
would fail. Running the program a second time worked. This
sequence is repeated the next time st-flash/st-util is run.

Giving reset 10ms to complete before trying to read the chip
version resolves the issue.
