Hi,
I try to get DMA in link mode working, but when DMA is enabled, the DER bit of the Channel Status Register is set. According to the user manual, this bit is set when the LV (Link valid) bit of the descriptor is 0 when it is being read by the DMA controller. In my code (attached) the Next Link Address is set to point to a descriptor in memory for which the header value is 0x00000001 (DIM = WBD = LE = 0; LV = 1).
Has someone an idea about what I did wrong or has anyone a working example (I could not find an example for DMA link mode)?
