Hello,
Does anyone have a success storry with this topic?
I'm trying to implemnt USB-CDC on LPC1343 using LPCUSB stack. I maneged
to pass the enumeration but after that point I have interrupt flood.
My setup is like this
- Olimex LPC-P1343 board
- Total Phase Beagle 12 USB analyser
- arm-none-eabi-gcc v4.5.0
- CodeBlocks IDE (with custom Makefile)
- debugging using printf (I have J-Link but OpenOCD can't do SWD with
J-Link :-( )
In Beagle Data Center after enumeration (ending with GET_LINE_CODING and
SET_CONTROL_LINE_STATE) I see only IN/NAK and that is OK because I did
not send anything.
But in MCU I have flood of interrupts for BULK_IN_EP, something about 89
interrupts in only one USB frame so my main loop is executing with a
speed of wounded snail :)
