help with OMAPL138 SYS/BIOS and starterware USB

Other Parts Discussed in Thread: SYSBIOS

hello there,

i'm trying to get usb working within sys/bios and evmomapl138 with starterware.

first i tried to get starterware standalone usb bulk device runnig by using the example from starterware. it worked out of the box for me.

now i want to use starterware (1.10.04.01) usb drivers within sysbios (6.37.02.27). i started with the "typical" example from SYS/BIOS as a base and added a hwi with Interrupt number 85 and USB0DeviceIntHandler as ISR.

then i added the sourcecode according to the standalone example to my project. i also compiled the necessary libs (drivers.lib, platform.lib, system_config.lib, usblib.lib and utils.lib) and added them to my project. the project builds fine. but if i start my application in debugging mode it does not run.

while debugging i noticed it hangs during USB Module clk enable in function PSCModuleControl.

the according line is nr 79 in psc.c

HWREG(baseAdd + PSC_MDCTL(moduleId)) = (flags & PSC_MDCTL_NEXT);

i don't know what here the error could be...

does anybody have an idea according my problem?

thank you for your help

Hi,

It is bit difficult to say that what could be the problem.

Better to integrating the small starterware code like UART instead taking bigger starterware code such as USB to test the PSC module control function (while integrating starterware code with SYSBIOS.)

It could be the problem of improper linking of usblib(mapping),

hi...

thank you for your response!

i managed to get the essential parts of starterwares rtc example working (with hwi interrupt).

didn't try the UART example. think i'll give it a try...

what exactly do you mean by "improper linking of usblib" ?

We do not have PSC module for RTC and try the UART starterware code or any simple starterware code to integrate with SYSBIOS,

If possible, attach your final integrated code (UART) to validate.
