I try to debugging IC V9881D use J-link JTAG module. I connecting J-link cable to pin MODE1, TDO, TDI, TMS, TCK, VDD5, RSTn, and LDO33 of IC V9881D. I use urJTAG software and Debian OS, but I have some problem like a picture. Could you guys help me to solve the problem?
I designed a kind of SWD & JTAG Isolater for Jlink & STLINK, for online debugging.
This may keep person and PC USB port from PCB board burning.
Can be used in Motor Control, Digital Power and some high-voltage applications.
IDE: Keil, IAR, Jflash, STM32 ST-LINK Utility；
I have some devices which have an ATtiny1634 on them and an ISP header. I want to be able to program them all at the same time rather than repeatedly plugging in devices and pressing a button. I understand that a "JTAG Daisy chain is the way to go but I'm not sure how to implement it.
