Read MC68HC11KA4 with FT2232HL?

**zappaf** · 25th May, 2020, 08:48 PM

Hello,

I'll try to read dump from processor MC68HC11KA4, but I dont know if it's ok with my FT2232HL board. I glued the wires, but I don't know exactly how to connect rx, tx and reset on my FT2232HL board.
Can I find the code by serial? Thanks

You choose oscillator the correct frequency ? In software the same as on board ?

I dont have (I dont find it) oscilator on FT2232HL board. On Program I choose 8.664MHz. RX and TX it's ok on vwz2z2 board. RST the same. But I must connect 5V on pin 1? And conect radio on 12V?
Thanks

Nothing.
It's correct? Like in picture.

Don't forget MODA and MODB. Both on GND.

Pin 59 and 60? Both are ground (-) on FT2232 board and radio. It's connect ok (on picture)?
Thanks

Then must be easy. Connect Moda A and Moda B at GND, Connect Rx from interface to Tx from MCU, Tx from interface to Rx from MCU, Reset at Reset. You put power on the radio but not ON.
Seelct correct COM to your interface and I recommend to change Quartz ...put 8MHz and select 8MHz . And Boot MCU. And Read MCU after boot successful.
Good luck.

I'll try to change rx to tx.
Thanks.

I changed rx with tx, but no succes.
But I have a question; with 59+60 (modA modB)connect together on ground the radio not start (no light, no SAFE), only little red led flashing. Without pin 59+60 connect together, when I put 12V radio light and SAFE (when button PWR push). I made something wrong? Does the radio have to display something when both pins (59+60) are connected to gnd?
