Part Number:TMS570LS0432
Hello,
I am experiencing an issue with a custom board of my design that uses the TMS570LS0432. JTAG is used as the method for programming/debugging and I am using a J-Link EDU debugger. I have received the error shown below from J-Link Commander and am kind of at a loss as to what I could be doing wrong. I've referenced the schematic for the TMS57004 and there's nothing different between my debugging circuit and the one on the Launchpad.
I am using a 14 pin header for JTAG on my board (schematic of the header shown below) along with a 2.2k pull up resistor on nRST, nPORRST, and a 2.2k pull down resistor on nTRST. There is a misnomer on the schematic where "-3.3V" should be labled "GND". I have also checked the TDI, TDO, TCK and RTCK lines from the JTAG connector on my board and have attached the captured wave-forms below.
MCU_TDI
MCU_TDO
MCU_TCK
MCU_RTCK
Any help on this issue is very much appreciated.
Thank you and Regards,
Michael Dewell
