26	Segmentation fault when initiating a DMA transfer	alexandre.chagoya-garzon@…	Nicolas Pouillon	"Hello,
I have a problem when initiating a DMA transfer. I attached the platform (top.cpp, segmentation.h, platform_desc) and the application  (MJPEG.x)

Everything runs smoothly, until a DMA transfer is initiated:
[fetch_process] Send SOF info to LIBU and IDCT
DMA transfer from 0x1004e620 to 0x1005779c (8 bytes)

I verified in vci_dma.cpp
134  VciInitSimpleReadReq<vci_param> *req =
135         new VciInitSimpleReadReq<vci_param>(
136             &m_data[0], m_src+m_offset, burst );
The correct src address is used, but on te next transition, a segmentation fault appears

Program received signal SIGSEGV, Segmentation fault.

Thank you for your help
