Hi,

I would like to understand how AINTC is configured for Logic PD eXperimenter Kit ?

I don't see it inside UBL, so I guess it could be inside the secondary bootloader (U-Boot) or Linux kernel.

Not sure where I can find it.

rgds,

Actually, what I want to know is how to setup the system interrupt for USB0_INT so that it will vector to my ISR.

I have done the initialization as following the BSL code from LogicPD (which is the same as in "TMS320C674x/OMAP-L1x Processor Universal Serial Bus 2.0 (USB 2.0) Controller UG (Rev. H)" 3.1 User Case 1: Example of How to Initialize the USB Controller).

And when I connect the board to PC USB port, it can be detected but report with "USB Device Not Recognized".

I just don't the way to setup the system interrupt for USB0_INT.

Hi Kiung,

There are examples that illustrate the use of the AINTC and how to map system interrupts to the IRQ host interrupt located here: http://processors.wiki.ti.com/index.php/QuickStartOMAPL1x_rCSL

Hope this helps!
