Develop MK22FN128xxx10 use SDK1.3 UART

UART_DRV_SendDataBlocking(uartCom_IDX, (uint8_t*)("this is a"), 9, 50u);

The receiver can only receive a bunch of "tttttttt..." , Use UART_DRV_SendData() enter an infinite loop, output one letter "t" at a time

Hello Thooman Wang

you need to install interrupt handler.

1] if you are using processor expert then enable "Install Interrupt".

2] If using KSDK without processor expert you can add it manually.

* API is :

osa_int_handler_t OSA_InstallIntHandler(int32_t IRQNumber,osa_int_handler_t handler);

* For example for UART1:

OSA_InstallIntHandler(UART1_RX_TX_IRQn, uartCom1_IRQHandler);

* Handler can be write as follows....

void uartCom1_IRQHandler(void)
{
UART_DRV_IRQHandler(UART1_IDX);
}

Let me know if any...

Thanks & Regards,

Hello

I have attached simple UART application code for K20. I hope it may help.Take a reference of k20 UART code you will get solution...

as i found no need to install tx_callback.

if still you found any issue..then share your code i will look into it and fix it.

regards,

Harsh

My software can work correctly on FRDM - K22, The same software can't run on MK22FN128xxx10, software configuration USES is KDS3.2, KSDK1.3 library have compatibility problems

This error has nothing to do with whether to use tx_CALLBACK, I have tried
