Hi all,
I'm trying to make faster flash writes happen on a mips based
platform -- because this is crazy: wrote 524288 byte from file
/root/flashme.bin in 45807.718750s (0.011177 kb/s).
I've downloaded the svn snapshot (2734), applied the "FASTDATA" bulk
write optimization, and made the necessary changes in my target to
add a working area. (mww and mdw show me able to modify values, read
them back, etc.)
(the target line is: target create $_TARGETNAME mips_m4k -endian
$_ENDIAN -variant ejtag_srst -chain-
position $_TARGETNAME -work-area-phys 0xb0100000 -work-area-size 0x1000)
When I try to write flash, I get this error:
Debug: 260 36117 target.c:1108 target_write_buffer(): writing buffer
of 2048 byte at 0xb0100060
