Hi,

I just tried the USB Bulk project previously posted here on the forum. (Many thanks for that!)

I'm using the IAR KickStart with 4.30 compiler and STR711 board.

For some reason I don't get any USB interrupts. I have compared with the USB Mouse example and it generates interrupts both when starting the application and when connecting the USB cable to the PC.

Anyone who has any ideas about where to start looking?

Thanks in advance!

As usual, to enable something you need to switch power on, and to switch the clock on, and turn on the PLL clock, and PLL power, and have HCLK on the right pin, and set the right divisors everywhere...

I do not remember the details, but there is a bit in the boot config register, and you also need to enable each PLL, and seperately enable clock for each device attached to PLL.

On the other hand, it is very much possible that the clock divisors

are configured for a different frequency.
