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 my chip and probably it will be working ok. Please send me this file consist bootloader and firmware version 5.04.

Again, there is no bootloader file for you - no need.

Just place the UPD_FIRMWARE_Razberry_from_05_10_to_05_04_.bin at address 0x7800 and also put byte 0x01 (one byte) at 0x77ff (you can prepend this byte manually and write single file at 0x77ff).

After you put this back to your RaZ, it should go into downgrade to 5.04. But on guarantee this will work - we have never tried that.

Can you write at a specific address?

Send via help desk. Write that file in the eeprom starting from address 0x77ff (30718). Then put it back to RaZberry and power on it. Should work, but not 100% sure.

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 ?

again, there are no bootloader in the EEPROM. Anyway, you have already erased the EEPROM, so don't worry to erase it again ;)

There should be a seek option in your programmer
