Issue on T2080 RapidIo Sra demo DMA transfer error

frank7 · ‎11-14-2020

I have tested T2080 RapidIO Sra test demo，SRA demo DMA mode prompts transfer error.

"sra -test srio port1 core swrite 512 " core test command is normal ,but "sra -test srio port1 dma swrite 512 " dma test command is abnormal!

Has anyone encountered this problem?

Is anyone has any idea or suggestion on me?

The dma error message is as follows:

fsl-elo-dma ffe100300.dma: chan0: Transfer Error!

fsl-elo-dma ffe100300.dma: chan0:irq:unhandled! sr 0x00000080

Please check whether you build Linux Kernel with the following options selected.

Device Drivers --->
<*> Userspace I/O drivers --->
<*> Freescale Serial RapidIO support
<*> Freescale DMA support

If your problem remains, please provide further information listed as the following.

1. Which version Linux SDK are you using?

2. Would you please provide you Linux Kernel booting up log?

3. Do you have T2080RDB to verify images used on your custom board?

4. Have you tested DDR memory on your custom board? eg. use "mtest" to test DDR memory in u-boot.
