Hi folks,
I'm back again with an USB problem: We have changed our concerto (F28M35H52C) from revision 0 to the revision step B and my USB host mode does not work! We did not do any changes in the hardware, just replaced the microcontroller! The errata sheet lists three problems fixed in the current step but to me these don't tangent my problem. What happens?
As far as I have started debugging I can say that the USB is not configurated in host mode anymore! After the initialization functions the bit HOSTMODE in the register USBDEVCTL is not set and the bit DEV is toggling.
I use the identical software! I will go now debugging into the library sources...
I work with the usblib version 160 since the version 201 does not work (see )
I have tested the new usblib as well but it did not work either. The program will not stall since the library functions do not enumerate the device because the USB controller is not working as a USB host...
Any suggestions?
Regards,
Stefan
