Update ender 3 v2 re: GD32F303 variants.

Open berg-michael opened this issue 1 year ago • 1 comments

Ender started shipping GD32F303 based mainboards sometime in 2022. These require "Disable SWD at startup" to be toggled. This PR adds a note regarding this setting. The note is lifted from the ender3pro-2020 config file, but I changed GD32F103 to GD32F303 as I believe this is the chip used in these models.

Thanks for submitting a PR, generally the GD32F303 variants do not need that setting, only the GD32F103 ones.

It seems to be a weird quirk that the GD32F303 is a better clone of the STM32F103 than the similar numbered GD32F103.

This is why these configs have not been changed to say otherwise.

Thanks James

So it took finding @JamesH1978 's pinned post about the GD32F303 before I unchecked the "Disable SWD at startup" and was eventually successful in flashing Klipper to a GD32F303 board that came in an Ender 3 Pro (not a v2). What are the chances that someone can add a line or two clarifying the differences between the 'make menuconfig' process settings for the GD32F103 and the GD32F303 chipset 4.2.2 boards in both the Ender3v2 and Ender3Pro starting/example printer.cfg's in the Klipper repository?
