--- Comment #7 from Tomoyuki Sakurai <[email protected]> --- (In reply to Hans Petter Selasky from comment #5) things get clearer. there are several tools to upload firmware. https://github.com/MarsTechHAN/ch552tool https://github.com/hexeguitar/CH55x_python_flasher although i haven't looked at the sources yet, my guess is that, there is no kernel driver for the bootloader. when the bootloader is running, these tools directly talk to it using a protocol. -- You are receiving this mail because: You are the assignee for the bug.
