Blackfin BF537: SDRAM + MDMA problem

Started by jkh_cz June 19, 2006
I've problem with SDRAM write in parallel with SDRAM MDMA transfer -
MDMA transfer invokes DMA error. Is that an anomalie or is something
wrong with me? I've tried many combinations of relating registers
without succes. I need to start urgent MDMA transfer but I need to be
able to continue in main program in parallel with MDMA transfer. Main
program should write to SDRAM in that time. Can you help me?

processor: Blackfin ADSP-BF537 (EZ-KIT Lite) rev. 0.2, VisualDSP++ 4.5

Thanks
