From 46176304562951ec41b6c257124d88c6707f4c3d Mon Sep 17 00:00:00 2001 From: Leonard Crestez Date: Sat, 1 Feb 2020 01:53:35 +0200 Subject: [PATCH] tcl/interface/ftdi: Add imx8mp-evk internal JTAG interface The imx8mp-evk board has a FT4232H chip connected to the chip's JTAG pins. Switching between this on-board interface and the external ARM-10 connector is controlled by an GPIO which is behind an i2c expander connected to the same FTDI chip. Switching can be performed using the NXP bcu tool: https://github.com/NXPmicro/bcu Change-Id: Ic910515f76eaf09ea6d0f755b026fb09cf09ccfc Signed-off-by: Leonard Crestez Reviewed-on: http://openocd.zylin.com/5426 Tested-by: jenkins Reviewed-by: Tomas Vanek --- tcl/interface/ftdi/imx8mp-evk.cfg | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 tcl/interface/ftdi/imx8mp-evk.cfg diff --git a/tcl/interface/ftdi/imx8mp-evk.cfg b/tcl/interface/ftdi/imx8mp-evk.cfg new file mode 100644 index 0000000000..4e04e8cd7f --- /dev/null +++ b/tcl/interface/ftdi/imx8mp-evk.cfg @@ -0,0 +1,28 @@ +# +# Configuration file for NXP MC-IMX8MP-EVK on-board internal JTAG +# +# Using this interface requires enabling "remote mode" for the board using the +# NXP bcu tool (see https://github.com/NXPmicro/bcu) +# +# bcu set_gpio remote_en 1 -board=imx8mpevk +# +# The REMOTE_EN gpio is accessible through the same FTDI adapter but it's +# behind an I2C GPIO expander. +# + +adapter driver ftdi +ftdi_vid_pid 0x0403 0x6011 +ftdi_channel 0 + +ftdi_layout_init 0x00f8 0x000b + +ftdi_layout_signal RESET_B -data 0x0010 -oe 0x0010 +# Called SYS_nRST in schematics +ftdi_layout_signal nSRST -data 0x0020 -oe 0x0020 +ftdi_layout_signal IO_nRST -data 0x0040 -oe 0x0040 +ftdi_layout_signal ONOFF_B -data 0x0080 -oe 0x0080 + +ftdi_layout_signal GPIO1 -data 0x0100 -oe 0x0100 +ftdi_layout_signal GPIO2 -data 0x0200 -oe 0x0200 +ftdi_layout_signal GPIO3 -data 0x0400 -oe 0x0400 +ftdi_layout_signal GPIO4 -data 0x0800 -oe 0x0800 -- 2.30.2
