From 979dfd8e68f01e7d2b827588ae1c3b779ef72801 Mon Sep 17 00:00:00 2001 From: Francis Rowe Date: Sat, 16 May 2015 08:30:04 -0400 Subject: External flashing guides: don't refer to red. Colour blindness is real, and quite common. What's worse, 3.3V on an ATX PSU is an orange wire, not a red wire. Someone looking at "red" in the documentation might not think that you mean 3.3V live/hot (red is the standard colour), but instead they might connect the red wire from the ATX PSU which is 5V; this will destroy the flash chip. Also, red and orange look the same to most colour blind people. --- (limited to 'docs/install/x200_external.html') diff --git a/docs/install/x200_external.html b/docs/install/x200_external.html index e79ca84..1a6eb44 100644 --- a/docs/install/x200_external.html +++ b/docs/install/x200_external.html @@ -92,7 +92,7 @@ POMONA 5252 (correlate with the BBB guide) NC - - NC NC - - NC NC - - NC - 18 - - 3.3V PSU RED + 18 - - 3.3V (PSU) 22 - - NC - this is pin 1 on the flash chip === back (palmrest) on your X200 === This is how you will connect.
