From f3e82459a8ea0fa0ec92e458a92cd20effcfef3a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Michael=20Niew=C3=B6hner?= Date: Mon, 26 Apr 2021 23:46:53 +0200 Subject: [PATCH] docs/mb/supermicro/x11ssm-f: rework flashing section MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The board can be flashed without adding a diode by just leaving VCC unconnected. Rework the flashing section to describes that.
