RAM checksum error on COMxx (P1 Flip)

[francisbauer]

I just installed the 2.9.0 version of the Propeller-Tool onto my Windows 7 laptop.
For some reason I can't successfully load into RAM without getting a checksum error.
I've tried two different P1 Flip modules, which in turn use two different COM ports 31 and 39.
If I try using the 2.8.0 version of Propeller-Tool with the same P1 Flip modules and the same COM ports, everything loads fine.
If I load a P2 program into a P2 Edge with the 2.9.0 version, everything loads fine.

I've moved the original Propeller-Tool folder out of the way and re-installed 2.9.0 and I still can't get either P1 Flip to load successfully.
So what is causing the issue with 2.9.0 when working with P1 Flip modules?

Thank you for reporting. I verified the problem; it happens on my system too. It appears a change I made caused this problem and I failed to download to a P1 afterwards. I'm looking into it now. There were a number of structural changes I had to make to support one or more of the recent changes, including to how the compilation process works. It's probably related to that, though is certainly a surprise to me.

Found it and fixed it! Solved in v2.9.1.
