Somehow i got the impression that the CKS32F103C8T6 , also had 2 x 64K flash.

But someone here - has one that fails above 64K

Could be bad chip , or ??

Any of you tried those : CKS32F103C8T6.

Or is that another one to avoid on Ali/*bay

Yes, CKS are 64K only. For genuine STM32 (with most likely 128K), search the description for "genuine" or whatever. Some sellers offer 2 options : knockoff or genuine, at slightly different prices. Learnt it the hard way. Couldn't get Demonstrator GUI to work with CKS , but STLink did the job (bootloader flashing).

This being said, and apart from this, they seem to be working the same with 64K. But they didn't like the 100K+ firmware I wanted to flash.

Got 10 of these a couple months ago : STM32 on silkscreen, CKS on chip, unclear description. The next purchase, I was more attentive and got 128K ones ! No "genuine" in description or options, chances are it's CKS with 64K only (or something else).

There are other scams : see https://github.com/keirf/Greaseweazle/w ... es-gallery
