Hello ! Friends I am a novice to this group but not to this processor. I have been working on developing real time Concatenated FEC for Modems using 5402. I am facing a big problem in using DMA in ABU mode.Actually I want to enable A DMA CHANNEL in ABU mode when 2 channels are already working in the same mode and i donot want to restart them.How should I proceed Should I Initialise the context registers for DMAcs and then simply write DMPREC to enable DMA channels.After some time when I need the 3rd DMA channel to be started I write again to DMPREC.But this is not working and in my application, I need the same thing my application So Friends Please help me to get out of this problem.. I will be very pleased to help out nebody in his problems. Sincerely Inderjit Singh Arora |
