Can't update Firmware

[diemue]

Tried the same. But after upgrade to 2.2.5 i get alway the message "Could not retrieve data from remote serve" (http://IP:8083/expert/#/uzb)

@diemue
Did you run the bootloader and firmware update while in 2.1.2 before upgrading to 2.2.5?
I did a factory reset of the z-wave controller before all this. Be aware that this can fail. I have several Z-wave controllers and this i currently not my production unit so i could afford a failure.

Small followup on this topic.
After update to 5.16 i got instability issues in domoticz that uses openzwave. Previously it was fairly stable. Reverted back to 5.04 but for some reason it still does not work reliably in domoticz. With Z-way it is working fine.¨
All tests on raspberry pi 2 using Z-way image updated to 2.2.5 or latest release of domoticz on raspian jessie lite.

Do anyone know what was implemented between 5.06 and 5.16?

This is what my system says before I try to upgrade.

In another discussion I have suggested to first contact support@z-wave.me for advice!
They never publish what is in experimental features.

Wondering why the bootloader is different.

I have no idea, except for the fact that I am running v2.3.0-rc1 and I had updated to firmware 5.06 a month ago or so.

Try update to v2.3.0-rc1 and se if you can downgrade from there. Tried some later build (rc2 or rc3) but newer got it stable then. I am using openhabian on my test device at the moment and dont remember all.

But make sure to remove first 0x1800 bytes (6144) which are zero before writing it to 0x7800 address

But how downgrade to v2.3.0-rc1 ?
In update i must write "v2.3.0-rc1" ?

Copy paste "v2.3.0-rc1" without ""

I clear all memory in chip.

Oops... you killed all your network data. Hope you had a backup!

But tell me step by step how i must write it to my chip. If i done succed i write a manual on forum.

As mentioned, we have never performed that. No step-by-step instructions. No one have ever tried such a geeky way. We have Z-Wave programmers to do it.

1. Locate on the programming 6 pins: Vcc, MOSI, MISO, SCK, RST, GND. You need all but RST
2. Pull EEPROM CS (you have to locate it) to LOW to select the EEPROM on SPI.
3. Set up some Arduino or professional programmer (it MUST be 3V!!!!) to read//write into M25PE20 EEPROMS
4. Write at 0x7800 the .bin file above (full file byte per byte skipping 0x1800 = 6144 bytes)
5. Then write 1 at 0x77ff
6. Release CS
7. Pull RST to LOW and the release (to reboot Z-Wave chip)
8. It should update then and boot on 5.04 (it is the latest)

If it is too geeky, just send it us in Germany or Moscow.
