Very slow writing speed #13

impnet · 2022-10-28T11:29:20Z

Hi, i just update from v6.3.1.1 to v7.0 but there is problem with writing speed via FTDI.

v6.3.1.1 is super fast, write whole file under 1s, but v7.0 is so slow and write whole file around 160s.

I tried option -B 100 and -B 200. File was writed under 10s but it is 10× more than on v6.3.1.1.

Is there samo hidden option which i missing?

Hi! I'm having the same issue with writing/reading LOW speed via FTDI. How are you solving the problem?

impnet · 2024-01-26T13:45:38Z

Hi! I'm having the same issue with writing/reading LOW speed via FTDI. How are you solving the problem?

Nope, did not find any workaround. I switch back to version 6.3.1.1.

raspB975 · 2024-01-26T14:42:40Z

Solution:

This is a known version of the official MSVC build.
https://github.com/avrdudes/avrdude/wiki/Known-limitations-of-avrdude#known-issues-for-programmers

Use the MinGW version, but you need to switch the driver to WinUSB using Zadig.

https://github.com/arduino/avrdude-packing/releases/tag/7.2-arduino.1
Now v7.2 working fast.

Does not work.

If there is need to instal special drivers via some another software, then it is useless.

Reference: this is a known issue of avrdude MSVC build. Work-around is to use mingw build (you need to switch driver to WinUSB).
