Hello,
i initialize my UART and send some data from board to putty. It works fine.
I can send data from ke04z to putty.
I try send some character from putty to my board.
Always the same:
It is some problem with my receive irq. When RX irq occures - mcu stops on IntDefaultHandler.
How to set my RX irq correctly?
I tried to use library (sdk) and change it, still the same.
(I cant use SDK examples cause it is to big for my uC)
Regards!
Hi Tomasz
Do you use interrupts for transmission?
The KE04 shares an interrupt vector for Tx and Rx so if you are using Tx interrupts (that are working) the problem is not with the UART vector but it may be a hard fault (without a handler) due to how the rx data is being handled.
If you don't use Tx interrupts it is presumably due to there being no UART vector installed for it.
Regards
Mark
