note this is a 1.8V chip and that might be the cause of your problems.
If you don't have a voltage adapter between your CH341A and the flash
chip, a safety circuit in the flash will trigger and prevent erasing
(as that would damage the chip at higher voltage).

If you already have a voltage adapter, it might be a write-protection.
Make sure that all the input pins have a defined state and that the
/WP pin is at a high level.

Hope that helps,
Nico
