- Subject: [ECOS] about GDB download speed.
hello, everybody,
(sorry about my last mail.)
I have ported redboot to an ARM board with a FLASH
ROM in 0x00000000, and the redboot is running in ROM
mode. Debug function is OK, and the tftp download
speed is about 3 M bps. But the GDB download speed is
only about 75 K bps.
I have read the mail talking about speed up the
GDB download speed, and modified the packet size of
redboot GDB stub to 20K bytes,
(generic-stub.c)
// #define BUFMAX 2048
#define BUFMAX 20480
and set the GDB with the following command in the
console:
set download-write-size 20000
set remote memory-write-packet-size 20000
set remote memory-write-packet-size fixed
Why the speed is still so slow, does the mode of
run in ROM effect? BTW, I have never enabled the cache
of the CPU, does this effect?
Any suggestion is appreciated.
Best Reguards
Rich
