I can’t upload firmware via my ST-Link v2. ?

Make sure you follow exactly the steps and double check wire connection as per

how to upgrade

firmware

Note:

1) There are different version ST-Link v2. The white one as below is the most stable and

recommended one.

2) The white version ST-Link v2 such as below photo has different hardware version. The original

one doesn’t have 3.3v on pin 1/2 and the clone one has 3.3v on pin 1/2. User has to short pin19

(VDD 3.3v) and pin 1/2 (TVCC) for the original one so pin 1/2 has 3.3v power. Otherwise, the

original one will have problem to upload firmware to LHT65.
