Hi
I’ve written an application for RCM2200 in Dynamic C. I am using functions such as serCopen() etc. to set up serial port C, but none of these functions seems to allow one to set the interrupt priority for it. This port is connected to a Vinculum VDrive2.
I also have an interrupt handler on Timer B which I set to Interrupt level 1. However, it seems that during some interactions with the USB stick in the VDrive2, the Timer B interrupt is halted for 1-2 seconds.
When I disconnect the USB stick, all is fine. So it seems that the serial port interrupt level is not lower than that of Timer B interrupt?
How can one decrease the interrupt level of a serial port on the RCM2200, so that the level is lower than that of Timer B?
Thank you
