Honored ContributorHello slh47
Is your design working? Can you please guide me in how to write a driver in C for mSGDMA running on Linux at HPS. I don't know from where to start...anything would help. Maybe some code to start with would help. I have done the FPGA design with the mSGDMA connected to F2H_Sdram. I would really appreciate any help.
Occasional ContributorHi,
I am trying to implement triple speed ethernet in nios processor using modular scatter gather dma (msgdma) controller. I have build the qsys. For memory i have used ram. I have called 2 msgdma one for receiving in streaming to memory mode and one for transmitting in memory to streaming mode. I have done the interconnections in qsys platform and generated the HDL successfully. The sopcinfo file is also generated. Using this sopcinfo file i tried to generate the bsp. The bsp generates but when i try to build the bsp project in eclipse the build fails. It says that " fatal error. altera_msgdma.h. No such file exists."
I am using Quartus 18.1. I cannot downgrade to lower version as i have progressed a lot in 18.1 and now cannot migrate to a lower version because of dependency issues.
Actually this file is missing in alt_avalon_tse.h. The altera_msgdma.h exists in the installation folder of quartus 18.1 in c drive. But some how when i try to build the bsp it doesn't pick that file and throws the above mentioned error. I have tried to manually move altera_msgdma.h and altera_msgdma.c file into the incude and source file of the driver folder of the project file. After doing this the bsp builds, but the actual project build fails.
I am not using linux
Kindly guide
Regards
Av
