Can't update Firmware

[pepeEL]

But if you tell me that i must write at specific addres but tell me what must be write at adress which i skip ? Write FF in all other address ? Because when i erase my eeprom it write in all address only FF.

[PoltoS]

Any. Bootloader will check only for what is at 0x77ff and after.

[pepeEL]

But in file you can not write all data on correct address ?

[pepeEL]

Ok i modified file and move all content data from your file, move to address start 0x77FF. From address 0 to0x77FF i put all FF. After content data i also add all FF to end memory epprom. Then i write to epprom. Tommorow i put chip on PCB RaZberry and test.
This is my file after moded:

Recovery_OK_correct_UPD_FIRMWARE_Razberry_from_05_10_to_05_04__.zip

Tell me for what device is file which you send me: firmware_UZB_from_05_10b_to_05_06.bin ?

[PoltoS]

Congrats! I was really fearing you will have to send it to our lab. Cool!

The UZB is for USB dongle called Z-Wave.Me UZB. But this one require removing 0x1800 bytes, prepending 0x01 and adding 0x77ff of zeroes before.

Can you please help this person with your own instructions? https://forum.z-wave.me/viewtopic.php?f ... 484#p66484

Please explaine me more cleary because i dont understand... and tgen i try prepare file for this users to write to epprom.

Is any plan to release new stable firmware for Razberry Me GPIO ?

Tell me also...range on new RaZberry 2 is very better than on my RaZberry 1 ?

This file has 0x1800 zeroes before the f/w. So to make the correct file one need to:
1. Remove first 0x1800 bytes
2. Prepend one byte 0x01
3. Prepend 0x77ff bytes with 0x00

Means the file is:
00 00 00 00 .... 6144 bytes with zeros in total 00 00 XX XX XX ... more data ... XX XX XX
And should become:
00 00 00 00 .... 30719 bytes with zeros in total 00 00 01 XX XX XX ... more data ... XX XX XX

It is even not yet released by Sigma But if you upgrade bootloader and then the f/w, it will work. Better to wait for a release (around Feb)

Tell me also...range on new RaZberry 2 is very better than on my RaZberry 1 ?

IMHO, yes! About twice better
