Hi ,

I had the similar problem with you. I used the example code from st library called UART (interrupt mode). keil tool chain. UART0 interrupt only response once.I can't figure it out, please help.

Is this keil problem ?I attached the whole source codes.

Thanks

Hi,

Has any of you resolve the problem with the interrupt enable?

I'm having the same problem as you both. No way to enable the interrupts.

First, with the example from the ST library UART (interrupt mode) only one interrupt happens, before the micro freezes.

Then, if I change the start up file STR9x.s, no interrupt happens.

Thank you

If you are using the Keil toolset with RTX O/S kernel, be sure to check out the following article

http://www.keil.com/support/man/docs/mcbstr7/mcbstr7_ex_swlib.htm

It suggests that RTX is not fully compatible with the libraries provided by STR7 Firmware Library due to interrupt handling issues.

This might explain what you are seeing ...

Is that also true for the STR9 family?

If so, no way to use ST-like ISRs with the Keil's RTOS working?

So the ISRs should be set up with the Keil's format...

Thanks
