Problem after driver update

2008-02-15T22:17:26+02:00

OK, this is a bug in all versions from 2007-12-01 to 2008-02-05. It will be fixed in all future versions. This bug affects the 16.5 MHz module only.

There was a restructuring between these versions where common parts of the assembler module were moved to a single file. I have overlooked that one register was different in the 16.5 MHz module.

Can you contact me by e-mail (AVR-USB support address) so that I can send you a fixed version for testing?

Up to version 2007_10_23 the 16.5MHz driver works for EasyLogger.

Starting version 2007_12_01 there's the problem.

It's hard to compare these versions because a lot of re-structuring occurred between them. But as far as I can see, none of the changes should affect the 16.5 MHz module.

I currently don't have my EasyLogger board available, so I can't run my own tests. Can you please try the other releases between these two? Maybe it's easier to see the difference if only a few lines have changed. Please don't for get a "make clean" before you compile with the new driver.

Hi Christian,

I have run successfully EasyLogger.2007-07-19.zip.
I have replaced the drivers by the ones found in PowerSwitch.2008-02-05.zip with the described problem.

Is there something I can do for troubleshooting?

BTW: I have flashed the above powerswitch application to an ATTINY2313 with 12MHz and it works fine. But of course, there's not the 16.5MHz driver used.

Regards, Tom

Which version works and which does not? Maybe we have introduced a bug in one of the last changes...

Hi,

as I want to use usbSofCount in my Easylogger variant, I went about to upgrade to the latest USB driver.
I deleted the usbdrv directory and replaced it by the one found in the latest powerswitch files.
I DID NOT MODIFY usbconfig.h.

Recompilation went ok with 0 warnings and 0 errors, but the device won't connect with the new drivers. Changing back to the old drivers everything works fine again.

What did I overlook?

Regards, Tom
