Hello,
Sorry for confusion, I will explain step by step from the beginning.
The first problem was: after configuration and calibration the controller started to stop in the middle of the work. After resetting started to work again.
So I wanted to update the firmware using Updater ver 0.5 to solve the problem.
(System is Windows 7 x64bit)
Steps:
1. Trying to use last version of updater – updating to version 440.14
2. Updating process starts and seem to be complete.
3. After using the updater the board becomes unresponsive to coolterm, Chillipepr, and to updater.
4. Trying the Avrdude metod (without programmer) – result is … no result, many error lines in avrdude.
5. Trying to add -E function, no success. Board still non responsive.
6. Trying to use updater again – Verification error, lookup button doesn’t show the version number.
***(of course in the process restarting the computer, reinstalling drivers etc, using different computer to be sure there no problem with computer itself)
7. Getting to plan B with direct chip programming .
8. Trying to use Usbtinyisp and usbasp (witout Vcc output to tinyg and with logic level converter)
9. No sucsess.
10. Starting to write here 🙂
——————————————————————————-
11. Today I tried once again the avrdude (without programmer)
12. Some sort of success – board became responsive for Chillipepr with firmware version 380.08 (if updating to 440.14 with avrdude board is not responsive)
13. Trying to update from 380 to 440 with updater instead of avrdude – works.
14. Board becomes responsive to Chillipepr until I hit first command (like Jog x) and then board is offline.
15. Chillipepr gives advice to update to 440.15
16. Updating with avrdude to 440.15
17. Board responsive for some short time now (only in chillipepr) when I try to enter settings in chillipepr (axis and motors) and hit Save, the board gets offline (resetting the board, resetting the JSON, and again it works for some time).
Still not responsive to Coolterm.
So those are steps for now.
Thanks for help.
