My RaZberry again start working Thanks

I write to my all epprom memory chip this file which i upload in previous post and my RaZberry start working. This file is FW 5.04 no include bootloader. But for me all working OK

Very very thanks for @PoltoS Good Job Thanks

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_c...

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

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.

Butif i clear all address in eeprom it probably also clear bootloader... ?

In my programmer i probably can not write at specific address. You can not create me ready file to write to all address which has content fw and bootloader and other what need ?

But my programmer erase all memory in my chip eeprom beore flash. Erase not clean bootloader ?

If i write this file without changes it not start woeking ?
Can you change this byte in file and send me ready to write please ?

See above. One for UZB, one for RaZ. You need the one for RaZ I've sent you. There is no bootloader inside as you don't need it now. You need to restore the f/w first Ok i remove chip from PCB and now programming is ok. But please send me file in one file(bootloader + firmware). I can write this to...

But what is for razberry ?
