Description

Hi
I want to flash new firmware to a SST25VF512 but neither erase nor write works, reading current firmware works.

The programmer I used is this one CH341A Mini Programmer (https://www.onetransistor.eu/2017/08/ch341a-mini-programmer-schematic.html), mine has a CH341B (https://www.wch-ic.com/products/CH341.html?) that can work without the external clock using the internal one.

With this, MIT Licensed, windows program AS Programmer (https://github.com/nofeletru/UsbAsp-flash) everything works, reading, writing, deleting, enabling and disabling write protection.

My OS is Debian GNU/Linux Testing

Thanks
