flexprop version 5.9.4 doesn't load to P2 Edge on macOS without "-SINGLE" option

[dgately]

When trying to load any compiled binary during "Compile & Run on P2", a timeout error returns unless the "-SINGLE" option is added to the Run Command line in Configure Commands panel... This happens on .bas and .spin2 compile/run attempts.

$ /Users/altergator/flexprop//bin/loadp2 -p /dev/cu.usbserial-A601RZ6G -b230400 /Users/altergator/Desktop/rayTest.binary -9/Users/altergator/Desktop -k -T; osascript -e 'tell application "flexprop.mac" to activate'; exit 0 ERROR: timeout waiting for initial checksum: got -1 Try increasing the FIFO setting if not large enough for your setup Press enter to continue...

Attempt with "-SINGLE" option:

$ /Users/altergator/flexprop//bin/loadp2 -p /dev/cu.usbserial-A601RZ6G -b230400 /Users/altergator/Desktop/rayTest.binary -9/Users/altergator/Desktop -k -T -SINGLE; osascript -e 'tell application "flexprop.mac" to activate'; exit 0 ( Entering terminal mode. Press Ctrl-] or Ctrl-Z to exit. )

Thanks for the bug report. I don't have a P2 Edge to test with, unfortunately. Do you happen to know how large of a FIFO is required to make loadp2 work?

Is there a command line option to try different sized FIFO buffers? I'm using the current Prop Plug Rev E (with: FTDI FT231X USB bridge IC)

Yes, I think it's "-FIFO n", where n is the number of bytes. So you could try "-FIFO 1024" or "-FIFO 2048" and see if one of those helps.

Thanks

OK, tried "-FIFO 1024" and it succeeds loading RAM as well as FLASH! Looks like 512 is default at this time. Should the default be set to 1024? Or should flexprop's command configuration change or get a FIFO option?

I'll change the default to 1024. Thanks for checking this!
