Hello There,

Current i meet an issue when i enable the semaphore control in UDMA DRU Direct mode in Vision app test environmet.

test log 1: if i comment "initPrms.SkipGlobalEventReg = TRUE" it will show udma_init fail

test log 2: if i un-comment "initPrms.SkipGlobalEventReg = TRUE" "it will show event register fail"

I think this issue may related Sciclient configuration.

Besides, I also can enable "checking channelContext->waitWord" way. but this way is not the most efficient solution.

Could you please hel me figure it out! Thanks a lot!

The test code will sent to TI expert via email later

Best Regards,

Samuel

Hello Samuel,

You need to un-comment "initPrms.SkipGlobalEventReg = TRUE". This will allow you to pass beyond UDMA_init

Now regarding event registration, please remove event registration. I think even TIDL uses polling mode. For the time being, can you please use polling mode?
