Bootloader update problem.

[Mikhail]

When connecting the Pixhawk PX4 PRO PX 32 bit flight controller to the Mission planner, I made the mistake of agreeing to the Bootlauder update. Now I can’t flash the controller firmware for the model I need. Please, help.

Hello! I have now read all the instructions and maybe updated the bootloader, but the link http://pix.rctoysky.com/pixhawk-firmwar ... uv2_bl.bin does not work, the page it leads to shows a 404 error. You can get the px4fmuv2_bl.bin file somehow - then in another way, for example by email or receiving an effective link.

Thank you! The new link worked and I downloaded the file. It didn’t work to update the bootloader according to the instructions http://pix.rctoysky.com/how-to-update-b ... -card.html, I will order the JLINK tool.
Best regards, Mikhail!

with SD card to update bootloader, you should not erase the code. You use QGC to erase the code, so you can not update with SD card.

I flashed the bootloader using Jlink, but when loading the QGC program, an error appears. I am attaching a screenshot.
I can't figure out what I'm doing wrong
