Hardfault when using UART2 interrupt

Hello Dialog,

I am getting a hardfault error when using the UART2_Handler_func method in uart2.c. The interrupt handler enters uart2_rec_data_avail_isr() (when some data comes in) and then hardfaults somewhere in the uart2_rxdata_getf() method. How can I avoid this and get some data out of my UART2?

Thanks,
svl0822

Hi bensalemsaif,

Hi bensalemsaif,

Please use the UART2_Handler() in order to get the interrupts from UART2. As far as i can see in the SDK there is no implementation for UART_Handler_func() and i haven't seen a hard fault occuring when using theUART2_Handler.

Thanks MT_dialog

Hi 3alogics,

Hi 3alogics,

What is the issue that your have, please try to be descriptive about what you are experiencing ? There is no modification needed in order to use the interrupts from the UART, just check the uart2_async in the peripherals example in the SDK.

Thanks MT_dialog
