  • I am not using the original Segger JTAG cable, as the pinout on both the TMS57004 development board and my custom board are both different than the standard ARM 20 pin connector. The onboard debugger on the TMS57004 does not seem to cause any issues while debugging, and my custom hardware doesn't seem to have any differences in the debug department (other than not having another debug probe attached, of course). It's worth noting that when trying to connect to the my custom board, the light on t…

  • My serial number is 260112082. I'm using a custom board, but I have this exact same issue both on my custom hardware and the development board I have (TMS57004 Launchpad). I looked at the schematic and the only thing of interest that I was missing was some pullups, which I went ahead and rigged onto it with no change. I will say that a point of interest is that I didn't expose SRST to the JTAG header, so I'm going to put a flying lead on it and see if attaching that to the debugger will get me t…

  • Hello, I previously made a thread about flashing a TMS570LS0432 with a JLink Mini EDU; it turns out that if you pay attention to the datasheet/specs (which I obviously wasn't doing ), you'd realize that the Mini can only target Cortex-M. I went ahead and grabbed a JLink EDU (which, according to the product page, does support Cortex-R4) and am now attempting to program. However, the issue I'm running into now is basically the same problem I had before. Upon attempting to connect, I get an "IDCODE…

  • I must have not been reading the specs very closely when I ordered the EDU Mini; I didn't realize that it couldn't target Cortex-R. Thank you for your time!

  • Hello, I am having some issues programming a TI TMS570LS0432 with a JLink Mini EDU. The MCU is on a custom board, which doesn't have any obvious design flaws that I know of. I'm fairly certain that I have the debugger attached properly to the micro, but I am receiving this error message upon attempting to connect: forum.segger.com/index.php/Att…f138dbabd679e302f13106917 My voltage reference is 3.3V (actual value in this situation was somewhere around 3.298V, which I'm guessing is close enough). …
