I'm trying to program an ATtiny13A with avrdude, using an Olimex AVR-ISP500 programmer, through the 6-pin ICSP connector. However, I can't get it to communicate with my MCU. The user guide tells to use -cstk500v2, here is the log with this option: https://ghostbin.com/paste/8yx35, and here is the log with -cavrisp: https://ghostbin.com/paste/2rpx6 (the command is $ avrdude -cXXXXXXX -P/dev/ttyACM0 -pattiny13 -v -F). The chip signature changes, but it always starts with 0x88. Here is how it's connected: MCU side ICSP side

What might I have done wrong?

UPD: rearranged the wires like that:

[Vcc]  [MISO]  
[MOSI] [SCK]  
[GND]  [RST]

It now measures the voltage correctly, but is still unable to communicate with the MCU.

UPD2: uploaded the new log with wires rearranged.

UPD3: on each side, both red and black wires are connected to a power supply, red to Vcc, black to GND.

The programmer was too fast, -B5 solved it.
