DFU v7.x update bootloader - CRC error

[Oleh]

I'm using

• s110_7.1
• sdk 7.2
• DFU

updating application (application.hex + application.dat zipped) works fine, but when updating bootloader (bootloader.hex+bootloader.dat zipped) it always report an crc error at the end of upload.

am I missing something?

Thanks&Cheers

Have you seen the document titled "How to generate the INIT file for the DFU"? I can't remember exactly where I found it.

It specifies that you need to remove 2 lines in the HEX file before you generate the BIN.

:02041000EA 
:041014000C0030015

then generate the CRC for the BIN like normal. After that replace the lines in the hex file.

Thanks, Jeremy
