+New test series with script loop4. This differs from loop2 in that
+it uses "pld reconfigure" to return to standby, instead of
+power-cycling. If we still observe corruption with this test, then
+a software problem would be to blame.

 The log file records the console output from the M1, plus time
 stamps and cycle numbers written from the "loop" script.
+
+Update: there's another test, loop2, which performs a shorter loop,
+which still produces corruption.
+
+Update: loop4 does the same as loop2, but uses "pld reconfigure" instead
+of power-cycling. Since loop2 was used for a test run #2 (NOR unlocked)
+and a test run #3 (first 55 pages of NOR locked), there is no loop3
+script.
