134	134	1. We see a case the FT232 USB TTL adapter has reliability issue with the PC USB chipset(Intel). In this case, even above, it still has serious reliability issue for uploading. If this happen, change a PC or change a USB to TTL adapter will solve.

287	287	1. There are different version ST-Link v2. The white one as below is the most stable and recommended one.
288	288	1. 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 might have problem to upload firmware to End Node.
