these days, i run dm6467 with tvp5158 module. In gpp and dsp, i use the video_copy(xDM0.9) example, on the dsp, i use the edma to carry the data, but i can only carry twice when i use CE_DEBUG=2 to see it. after edma carry twice, tvp5158 on the gpp will stop running, i guess its thread blocking.when i replace the edma with memcopy ,it will work fine. and if i run origin video_copy app.out of the gpp, the edma will work well on the dsp too.
in tvp5158 code (gpp side), it have use the edma ,and on the dsp ,i also use edma, will this have problem?
does someone meet with or listened this problem?
