    Joel Fernades and you have been great at covering kernel debugging. Another great video. The only grouse I have with BeagleV-Fire, BeagleY, etc is the use of Tagconnect pins for JTAG. How hard is it to populate a 10 pin micro-jtag connector ffs?

      yeah, @turanamo I share the same peeve. argument is that JTAG users are very very few and far between.. and choice would have been not to populate the header (bbb style). But on the flip side, I do appreciate not having to run behind people to get them solder pins on my board.. just hate the economics of the cables..

    Any thoughts how you can dump the chip's memory to a file?
    I purchased a FlashPro4 jtag adapter to program a Cortex-M3, but not sure how all this works. From, what I see, OpenOCD is a GDB server running on your computer, but uses "fpserver" to talk to the FlashPro4 jtag adapter/chip?
    So while Eclipse can download the elf using OpenOCD , I can't telnet directly to that port using putty (4444) . Interestingly, I *CAN* telnet to fpserver on 3334, however that seems to be an undocumented API.. so kinda in limbo.

      Join us on IRC @ libera.chat and #openocd irc channel. It might be a better place to get clarification..

    Correction in Video: At approximately 5 minutes and 50 seconds, I say that the SoC is J721s2, also known as AM67. I'm afraid that's not right. It should have been: J722s is also known as AM67.
