Vcds Atmega162 Reflash

If it reads something else, apply the appropriate template matching your new firmware, fix the serial number, and click . Step 3: Writing the ATmega162 Flash and EEPROM Disconnect the USB cable from the PC.

Connect your USBasp programmer to the ISP pins on the VCDS board. Plug the USBasp programmer into your computer's USB port. Launch or Khazama AVR Programmer . Select ATmega162 from the device drop-down list. Setting the Fuse Bits

This is the core processor of the interface. It holds the actual VCDS firmware code in its flash memory and secondary configuration data in its internal EEPROM.

Once connected, plug your hardware programmer into your PC. Do not plug the VCDS cable into the USB port yet; the programmer will power the chip. Using Avrdude to Write Firmware vcds atmega162 reflash

Before starting, gather the necessary hardware programmer and software applications. Hardware Requirements

Some cables use 3.3V logic (if FTDI runs at 3.3V). Check voltage before connecting ISP. Using 5V on a 3.3V board kills the ATmega. If it reads something else, apply the appropriate

Write back the original fuse settings (critical):

Carefully open your VCDS interface casing. Visually identify the main processor chip on the printed circuit board (PCB). You must verify that the markings clearly state "ATMEGA162" before proceeding. Also, inspect for the presence of an "STC" chip; if found, it may need to be removed or disabled by cutting a circuit trace for the reflash to work.

Your cable is now a paperweight. The only recovery method is a full ATMEGA162 reflash . Plug the USBasp programmer into your computer's USB port

0x3C = Further programming disabled, verification disabled, memory read disabled.
