I am using 7z020, at Z-Turn from MYIR, with Linux,
my design has a 64 bit DMA to transfer data from Linux to the PL and back,
and it works until , about 1600*8 bytes (remember it is 64 bits data width),
then when I go higher it gets stuck at :
Memory-mapped to stream status (0x00001001@0x04): halted IOC_IrqStream to memory-mapped status (0x00005011@0x34): halted DMAIntErr IOC_Irq Err_Irq
I can attach my code, which uses registers to configure the DMA and send data, I am not using devices drivers.
People with similar problems said it DMAIntErr happens when the data received does not match with the length set.
