**** BEGIN LOGGING AT Wed Jan 23 02:59:57 2008 Jan 23 15:44:03 hello Jan 23 15:49:05 r00t-Ed: Hi Jan 23 15:50:58 hi drath, i wonder if you have a minute to ask you a couple of things about the xscale jtag Jan 23 15:55:16 heh, i wont guarantee any response times (i'm currently at work), but yeah, feel free to ask Jan 23 15:56:26 ok, is not that important, i am at work too, i grabbed a device that has an ixp425 and flash, it boots fine with redboot Jan 23 15:57:04 i wanted to actually backup the flash prior to start messing witht the image on the flash Jan 23 15:57:42 so i has the 20 pins jtag port, i see that it is common for the xscale base boards Jan 23 15:59:02 i build the cable, but now i am looking for a software that will allow me to do the flash backup Jan 23 15:59:48 we have a bdi2000, but i just realized that it is for a different target Jan 23 16:06:11 i found something about the jtag tool for linux Jan 23 16:06:21 but wonder if there is a better way ? Jan 23 16:06:50 if you just want to backup the flash, and possibly restore it at a later point, the openwince jtag tool should be fine for you Jan 23 16:06:52 can you backup stuff from redboot ? i see that you can load stuff from the tftp Jan 23 16:07:19 sorry, i haven't used redboot a lot Jan 23 16:07:44 ok me neither.. openwince, thanks i will look that up Jan 23 16:07:49 and in any case, you wont be able to restore your flash, once you've (possibly) broken redboot ;) Jan 23 16:09:25 i know, i was tempted to update the redboot, this is version 1.9 i found that they are in 2.5 or soemthing Jan 23 16:09:49 and it is easy to do,i just want to backup the flash before i start playing with it Jan 23 16:10:39 be prepared that using the openwince jtag tools is going to take quite some time Jan 23 16:11:19 i see, yes, i saw a post (that is how i got here) about 45 mins for 256kb Jan 23 16:11:27 this flash is 16mb Jan 23 16:11:40 there must bet a faster/better way i think Jan 23 16:12:07 well, there's xscale support available for the bdi2000, but you've got to buy a separate license for each target family Jan 23 16:12:55 alternatively there's the OpenOCD Jan 23 16:13:04 yes, i found that out very quickly, the one we have is for some ppc architecture Jan 23 16:14:46 people have successfully used the openocd to debug and flash ixp42x based devices Jan 23 16:15:29 but using the openocd (or the bdi2000 for that matter) places some additional requirements on the JTAG interface, and the target's reset circuit Jan 23 16:17:38 let me try that jtag from openwince, see if i can query the device and stuff Jan 23 16:18:22 allright, i'm on my way home now, bye Jan 23 16:18:33 bye thanks **** BEGIN LOGGING AT Thu Jan 24 01:05:20 2008 **** ENDING LOGGING AT Thu Jan 24 02:59:57 2008
