FASTUSBasp programmer for AVR Microcontrollers

This is the fast ISP programmer for AVR MCUs based on cheap stm32f103c8t6 aka blue-pill board with usb-to-serial support.

Release

• v1.0.0: https://github.com/amitesh-singh/FASTUSBasp/releases/tag/v1.0.0

FastUSBASPv2 board

Perf board

Correcting wrong pullup at USB D+

This blue pill board has wrong pullup resistor at usb D+ line. You might need to fix it before using blue pill as an AVR programmer. Refer to this guide: http://amitesh-singh.github.io/stm32/2017/10/09/correcting-usbpullup-resistor.html

how to upload firmware

blue pill board with correct pullup at USB D+ line

Download the binaries from https://github.com/amitesh-singh/FASTUSBasp/releases/tag/v1.0.0

If you have fixed the pullup at D+ line, use fastusbasp.bin The pre-compiled binary is at fastusbasp.bin.

$ st-flash write fastusbasp.bin 0x08000000

blue pill board with wrong pullup at USB D+ line

In case, you did not fix the wrong pullup at D+ line, use
fastusbasp-wrongpullup.bin binary instead

$ st-flash write fastusbasp-wrongpullup.bin 0x08000000

How to use

ISP connections

It uses SPI2 to communicate to AVR.

Blue pill	AVR
PB15	MOSI
PB14	MISO
PB13	SCK
PA8	RST
5v or 3.3v	5v
GND	GND

Serial connections

Serial ports are PA10(RX) and PA9 (TX).
This can be used to debug AVR Microcontrollers.

Blue pill	AVR
PA10	TX
PA9	RX

All pins SPI2(PB15, PB14, PB13), Serial(PA10, PA9) and RST(PA8) used are 5V tolerant.

udev rule

Refer to udev/README.md

Flash Read/Write speed

Flash Write speed: 15 KBps
Flash Read Speed: 52.5 KBps

Bit clock speed

FASTUSBasp starts out with a fast ISP clock frequency (default: 3 MHz), so the -B bitclock option might be required to achieve stable communication in case target MCU F_CPU is bit low < 12MHz

Supported bitclock speed

• default (without -B): 3 MHz
• 1.5 MHz
• 750 KHz
• 375 KHz
• 187.5 KHz

how to compile from source and upload the firmware

To build fastusbasp firmware from source code, follow below guidelines.

compile

Refer my post on how to setup stm32 devlopment environment on Arch linux. http://amitesh-singh.github.io/stm32/2017/04/09/setting-stm32-dev-environment-arch-linux.html

Make sure you have compiled libopencm3 library.

$ git clone --recurse-submodules https://github.com/amitesh-singh/FASTUSBasp
$ mkdir build
$ cd build
$ cmake ../
$ make

Upload the firmware

using STLINK

connect st-link programmer to blue-pill and upload the firmware

$ make fastusbasp-upload

using serial port

Install stm32flash utility on linux. To program stm32f103 via USART, you need to set BOOT0 as 1 and leave BOOT1 as 0.

Connect any usb to uart converter device and connect PA9 to RXD and PA10 to TXD and connect GND.

$ make fastusbasp-serialupload

fastusbasp's Issues

Make it work on any machine

Hello,
wanted to build it, but:

me@machine~/code/fastusbasp $ cat config.cmake
# Always declare this before stm32-toolchain.cmake
#
set(MCU STM32F1)
set(LIBOPENCM3_DIR "/home/ami/repos/libopencm3")
set(SERIAL_PORT "/dev/ttyUSB0")

No chance this will work here :)

Can you include libopencm3 in your source tree, or manage it as a configurable dependency via, eg, a cmake variable?

thanks

Reset after programming

First to say: Great project.
FASTUSBasp is way faster than my AVRISPmkII clone which I couldn't get working under Win7-64 anyway.

Now my issue:
I'm using AVRDUDESS / Win7-64 to program an ATmega328p. Everything is working well.
But after any action the reset line stays low, keeping the microcontroller in reset state. What I'm doing wrong?
Please help.

avrdude error

the stm32 drivers are successfully installed and the device appears in the device manager on Windows10, but I get this error whenever I try to invoke avrdude using "avrdude -c usbasp-clone -p m8 "

Avrdude for Windows: Can't find programmer id "usbasp-clone"

it seems there is no programmer type "usbasp-clone" within windows release of avrdude. Is it possible to solve this?
I've got avrdude here https://sourceforge.net/projects/winavr/

Seeing this error upon compilation on WLS (Windows Linux Subsystem)

Howdy,

Thanks for this cool project. Lot's of interesting embedded C++ going on!

I have this error just now ...

I think I'm compiling OK, but there is an error in the final (no pun intended) link step.

Compilation under Ubuntu 19.04, as a Oracle Virtual Box VM works fine.

Best,

Firmware for ST-Link clone

Hi,

I've two question to your firmware:

• Is it possible to directly flash it onto a ST-Link clone or are there some small changes needed? https://www.hobbiton.be/blog/repurpose-stlink/
• Does it support the TPI programming for the small attiny4/5/9/10?
  Best, trembel

Verify FASTUSBasp on Windows OS

I don't own a windows PC at home. It would be nice if someone helps in validating FASTUSBasp on windows OS.
