9009 no-os project ADC to mem

xlh on Oct 19, 2020

Hello~

Does the dac to mem example in 9009 no-os project should provide data to RX interface external such as by signal genetator? For when I connect TX1 with RX1 and then cancel comment of both DMA example and adc to mem example，and add ILA in vivado，I just see waveform appear in the output of tx_dma, but nothing can be found in output of rx_dma（the value of 0）?

Any help should be appreciated!!

Hi xlh,

You don't need a signal generator. Data is sent over TX1 using DMA from a sine LUT table. If you physically loopback RX1 and TX1 you will see the waveform at RX1.

Thank you, another problem confused me that why the link status become CGS sometimes, and DATA sometimes(this is normally work mode, yes?). How to debug this problem?

A dedicated thread regarding this problem is available: https://ez.analog.com/microcontroller-no-os-drivers/f/q-a/536921/9009-jesd-stay-in-cgs

Please don't open multiple threads regarding the same issue. It's very hard to track all the updates/answers - it only complicates the situation.

Thanks,
