I'm trying to load NOR flash on my DM365-based board using the emulator (TI PCI XDS560, JTAG clock set to 10 MHz).
I'm seeing very slow data transfer rates from the host using fread() - about 6 KB/s. JTAG clock seems to have disproportionally small effect on this: with 1.5MHz the data rate was about 3 KB/s. Those are just data transfer rates, flash writes are excluded.
On the other hand, loading an .out file is performed at approx. 10 times higher rates through the same emulator.
Is there any way of speeding up the fread() data transfer?
Thanks.
