<div class="moz-cite-prefix">I finished first tests on memory read
performance fot jtag probes/pic32, all on my Mac except the
raspberry test:<br>
<br>
Olimex TINY-H with openocd: 120 Seconds for 32k of data<br>
Olimex TINY-H with ejtagproxy: 10 Seconds for 1k of data, I did
not have the patience to wait for the transfer of 32k ;-)<br>
<br>
Raspberry PI with openocd in gpiomode: 50 Seconds for 32k of data<br>
<br>
J-Link Edu with openocd: 30 Seconds for 32k of data<br>
<br>
mikroProg from Mikro-E: approx. 8 Seconds for 32k (but no
gdbserver and ICD Protocol on windows, only for reference)<br>
<br>
ST-Link2: not yet tested.<br>
<br>
pickit3 on ejtagproxy: not yet tested <br>
<br>
I had high hopes for the Raspberry Pi solution because there's no
USB transfer involved, sniff.....<br>
<br>
J-Link performance is not stellar, but will be good enough for me
right now.<br>
<br>
If anybody has better results, please feel free to share on how
you were able to get better performance.<br>

I etched some testboards yesterday and connected them to my
ARM-USB-TINY, openocd detects the chip just fine but Michel was
right, flash read performance is a mess, it took two minutes to
read out the 32k flash of my pic32mx220 chip, that's pretty
slow. I will check if a j-link or st-link work better, but I do
not have high hopes. <br>
<br>
But perhaps the ejtagproxy or pic32prog can solve this problem,
will keep you posted.<br>

Maybe this helps....<br>
