DMA data transmit from parallel flash to EPPI on BF548

HI to All!

My question is:


What is the most fast and effective way to transfer data from BF548 EZ-Kit PC28F128 flash to EPPI peripheral

connected to some kind of FPGA?


The relevant examples I found VisualDSP 5.0 package are:

"Flash Programmer" and "ezkitBF548_initcode_ROM-V02.dpj" .

(The "Flash Programmer" uses VisualDSP++ 5.0 Device Drivers and System Services.

And "ezkitBF548_initcode_ROM-V02.dpj" manages flash directly, without API library.)


I assume that I have to config the EBIU:



Also I would like to know - what is the effective block size in order to transfer 1GByte of data?

Also the EPPI mode I plan to use  is "GP FS1". But how exactly  this Frame Sync works. Does it

triggers callback routine at frame end?


Thanks and best regards,
