From 44394c2a77f68785e2ec87e2245d0f1624086682 Mon Sep 17 00:00:00 2001 From: Paul Fertser Date: Wed, 10 Sep 2014 12:29:23 +0400 Subject: [PATCH] interface/ftdi/olimex-arm-usb-ocd-h: fix nTRST control definition According to my inspection of an Olimex ARM-USB-OCD-H adapter ACBUS0 is connected directly to an SN74LVC2T45 buffer input B2, and the corresponding output A2 is connected directly to the JTAG connector. It seems the information in the Olimex flyer is incorrect for the -H version and TRST can't be tri-stated, ACBUS2 is unused. The older ARM-USB-OCD device has SN74AC244 for an output buffer and ACBUS2 controls its !2OE, ACBUS0 connected to 2A1 (2Y1 is nTRST), in accordance with the information flyer.
