Download the avrdude.conf from our bitbucket.
Use the following commands

env.sh configure chip type probe.sh detect the chip and connections flash_dump.sh read flash flash_write.sh flash flash

Modify avrdude.conf for RPI

Linux GPIO configuration for avrdude.
Change the lines below to the GPIO pins connected to the AVR.

programmer
  id    = "linuxgpio";
  desc  = "Use the Linux sysfs interface to bitbang GPIO lines";
  type  = "linuxgpio";
  reset = 12;
  sck   = 24;
  mosi  = 23;
  miso  = 18;

SWD - STM32

env.sh Configure the platform to which the chip belongs, such as stm32f1x, stm32f2x, etc. When calling other scripts, you need to execute source ./env.sh first to initialize the environment variables, the same below.
probe.sh is used to detect the existence of the chip
attach.sh attach to the chip, then another window can call $telnet localhost 4444 for single step debugging
flash_dump.sh dumps the flash data from the chip
flash_erase.sh erase flash data in the chip
flash_write.sh Flash inside the chip
lock.sh stm32 series chip provides flash write protection. After the write protection is turned on, the chip cannot be debugged. The flash data is read. The product commercial recommendation is to open the write protection function.
unlock.sh cancels write protection.

I2C and SPI

Flash

probe.sh detect the flash type
flash_dump.sh read flash
flash_write.sh write flash

EEPROM

Please notice V1 version use I2C0, V2 version add selection to I2C1

env.sh Configure the chip model, you can call avrdude -p ? to view the currently supported chips.
probe.sh probes the i2c bus
flash_dump.sh read flash
flash_write.sh flashing flash

OR use I2CDetect to direct dump, write, and read
