edma_transfer definition question

海雄周 — Wed, 15 Nov 2017 01:31:27 GMT

Hi,

I have a problem at using the "edma_transfer" function. In the example of edma_transfer, the edma_transfer.h has declared "triggerDmaUartTx(uint8_t channel, uint8_t * buff, uint32_t size); and triggerDmaUartRx(uint8_t channel, uint8_t * buff);" However, I don't see the specific definition, and it don't work without the specific definition. So, I am asking the original code for those two functions if any one can help. Thanks.

Sincerely,

Zhou

Hi,

In the sources folder of the examples, you should find edmaTransfer.c which contains the definitions of those functions.

Best regards,

Rares

Hi:

edmatransfer.C there is no triggerDmaUartTx (uint8_t channel, uint8_t * buff, uint32_t size) and triggerDmaUartRx (uint8_t channel, uint8_t * buff) the definition of two functions

Hi Rares

I have the same problem. The functions triggerDmaUartTx/triggerDmaUartRx are only in the h-file not in the c-file.

I checked S32 Design Studio for ARM v2.0 and the S32 Design Studio for ARM® v2.0 Update 2 – S32 SDK 0.8.5 EAR & MQX as well.

Help would be greatly appreciated!

Thanks Henning
