41CL: Plugging a Module from RAM rather than FLASH?

Hi Monte, I definitely did not take any special steps to engage Turbo mode (let alone Turbo50), so maybe this is the source of my problem. It's not automatically built into YIMP, correct? Should Turbo50 be utilized when flashing PC to 41CL as well? I don't think it's mentioned to engage Turbo in the clupdate text file, but maybe I just missed it.

I should mention I didn't see OVERRUN on the initial upload, but only in repeat attempts after the first. The first time it seems to go through without error, but the CRC tests bad.

I had repeated the same bad CRC results (well not sure if it was the same bad number each time, but it was incorrect) a few times, but it was different sessions, with SERINI between them. Now I understand that it was the SERINI between sessions that cleared the OVERRUN error. That's really helpful, thanks!

I'm tied up until Monday unfortunately, but will retry it then with Turbo50.

Thanks!

OK, I tried this again using my same procedure steps at top, but now with Turbo50 set (and verified to be 50 via TURBO?).
Unfortunately, I still get a different YCRC checksum every time I execute the upload from PC→41CL RAM.

When I am doing the upload, the feedback in the clupdate DOS window looks fine:
•It gives the proper checksum,
•opens COM1,
•waits 5 seconds before starting transfer,
•transfers 8192 bytes as 2408 2408 2408 968 = 8192
•closes COM1.

On the 41CL side, I am a little less sure all is OK. I get "RECEIVING", but then after clupdate is done and the host closes the COM port, the 41CL just eventually reports "TIMEOUT". I'm not sure if this is normal or if the 41CL should know that the host has completed and report back "TXFER DONE" or anything like that. The terminal "TIMEOUT" doesn't feel "warm and fuzzy" to me.

The suggested use of SERINI (and it seems an OFF-ON power cycle) did seem to clear the OVERRUNs when they occur. They don't occur every time, though. In any case, I don't see any notice of them having happened until afterward if I retry the YIMP; then the 41CL reports it's in an OVERRUN state.

Thanks, all.
