    [SOLVED] How to manage JTAG Vcc (5v) and the target Vcc (3.3v)

    I am trying to connect JTAG to MIPS 24Kc SoC which has 8 pin out of the board. The pins are- TRST, TCK, GND, TMS, TDI, VCC, TDO, RST. My JTAG device is FTDI2332 based, 20 pin, ARM-USB-OCD from Olimex. The router's onboard Vcc pin (jtag) is 3.3v when JTAG debugger's Vcc is 5v. Unlike the 20 pin...

    [Moved]: Need help understanding CT pins in RJ-45 with magnetics

    I understand. So far I can see, that part should be already implemented on the LAN card. So, should I just GND pins (TXCT, RXCT) going to PHY?

    [Moved]: Need help understanding CT pins in RJ-45 with magnetics

    Hi, I'm trying to reuse some old unused LAN cards to connect to some microcontroller evaluation boards with ethernet support. I chopped off the PHY while keeping the rest. I am treating the RJ-45 to PHY circuitry as blackbox, while dealing with the wires coming out the transformer connecting...
