14:22 <ScottBakula> Hello everyone :D

14:22 <ScottBakula> good to see people already using irc !

14:22 <PaulFertser> Hey!

14:24 <ScottBakula> i found the server because i am looking for informations regarding openocd and the linksys wrt54g, i am in cybersec and learning about iot reverse engineering.

14:24 <ScottBakula> i was trying to halt the cpu on this board but it seems it's not so easy

14:26 <ScottBakula> do you know what it means : > halt

14:26 <ScottBakula> MIPS32 only implemented

14:26 <ScottBakula> target halted in MIPS32 mode due to debug-request, pc: 0x8021fa90

14:46 <PaulFertser> ScottBakula: haha, you picked quite an old target for REing.

14:46 <PaulFertser> ScottBakula: so, it halted, you can inspect memory etc, what's the question?

14:46 <ScottBakula> ok i think there is a nTRST switch to create , yeah @PaulFertser

14:47 <ScottBakula> https://sergioprado.blog/images/20200220-wrt54g-jtag.png

14:47 <PaulFertser> ScottBakula: btw, for reliable reflashing of wrt54g see the tricks in tools/firmware-recovery.tcl

14:47 <PaulFertser> ScottBakula: nTRST is optional to reset JTAG state machine, same can be done by state transitions.

14:48 <PaulFertser> Looks like the board has integrated pull up so you can just leave it alone?

14:49 <ScottBakula> interesting file firmware-recovery.tcl @PaulFertser

14:55 <ScottBakula> i am using a flipper zero with DAP Link app, and openocd of corse. I tested it with an esp32s2 and it was working properly, it emulates a USB CMSIS-DAP

14:57 <Haohmaru> uh, isn't your target JTAG-ish?

14:58 <PaulFertser> Cool, so Flipper zero is useful for something after all :)

14:58 <PaulFertser> CMSIS-DAP supports JTAG

14:58 <Haohmaru> yes but do such exist?

14:59 <Haohmaru> i think i've seen only those with SWD

14:59 <Haohmaru> but maybe i've been looking thru a straw

15:03 <ScottBakula> yeah it's nice @PaulFertser

15:04 <ScottBakula> i am progressing with the firmware-recovery, it seems i can list partitions

15:06 <ScottBakula> https://pastebin.com/je9gveaZ

15:06 <ScottBakula> same troubles :'(

15:06 <ScottBakula> it looks like the cpu can't be halted

15:30 <ScottBakula> dump_image seems to work , cross fingers :D

15:42 <ScottBakula> 1h left it seems long but let see if we can get this firmware out of this box

17:40 <gamiee> ScottBakula> good to know that CMSIS-DAP works well with JTAG :)

20:37 <borneoa___> zapb_: proc "target hello" {} {echo "hello target"}

21:20 <zapb_> borneoa___, awesome, thanks!

21:32 <ScottBakula> @gamiee, hello, i am not sure it's working properly, is there any commands to check the jtag ? i tried to dump the image from my wrt54g but it looks like buggy, the command has been executed successfully but the binary is empty (binary size is good but nothing in it)

23:28 <karlp> where did you even find a wrt54g?
