-- gerrit commit 5e84f73f201f9d98cc660e47c51cdf3dae4c6644 Author: Peter Griffin <[email protected]> Date: Mon Jun 12 16:28:03 2017 +0100 tcl: add hi3798CV200 target and Tocoding Poplar board config This config covers the 4x Cortex A53 CPUs. A custom connector is required from J14 to standard ARM JTAG on v1 boards. However v2 hardware should have a standard FTSH-105-01-L-DV connector. Pinmuxing code to enable JTAG pins is included in l-loader-poplar repository, so board is flashed with open source code, JTAG is available at very early boot. Alternatively the following pokes can be issued from U-Boot to enable JTAG (e.g. to debug hisilicon SDK). mw 0xf8a210ec 0x130; mw 0xf8a210f0 0x130; mw 0xf8a210f4 0x130; mw 0xf8a210f8 0x130; mw 0xf8a210fc 0x130; mw 0xf8a21100 0x130; Change-Id: I2b83dfcb3dc5461c1620f94dd99aa7b31fdda59b Signed-off-by: Peter Griffin <[email protected]> diff --git a/tcl/board/tocoding_poplar.cfg b/tcl/board/tocoding_poplar.cfg new file mode 100644 index 0000000..4ad3bf5 --- /dev/null +++ b/tcl/board/tocoding_poplar.cfg @@ -0,0 +1,28 @@ +# +# board configuration for Tocoding Poplar +# + +# board does not feature anything but JTAG +transport select jtag + +adapter_khz 10000 + +# SRST-only reset configuration +reset_config srst_only srst_push_pull + +source [find tcl/target/hi3798CV200.cfg] + +# halt the cores when gdb attaches +${_TARGETNAME}0 configure -event gdb-attach "halt" + +# make sure the default target is the boot core +targets ${_TARGETNAME}0 + +proc core_up { args } { + global _TARGETNAME + + # examine remaining cores + foreach _core [set args] { + ${_TARGETNAME}$_core arp_examine + } +} diff --git a/tcl/target/hi3798CV200.cfg b/tcl/target/hi3798CV200.cfg new file mode 100644 index 0000000..5c8fbb7 --- /dev/null +++ b/tcl/target/hi3798CV200.cfg @@ -0,0 +1,49 @@ +# Hisilicon Hi3798CV200 Target + +if { [info exists CHIPNAME] } { + set _CHIPNAME $CHIPNAME +} else { + set _CHIPNAME hi3798CV200 +} + +# +# Main DAP +# +if { [info exists DAP_TAPID] } { + set _DAP_TAPID $DAP_TAPID +} else { + set _DAP_TAPID 0x5ba00477 +} + +# declare the one JTAG tap to access the DAP +jtag newtap $_CHIPNAME dap -irlen 4 -ircapture 0x1 -irmask 0xf -expected-id $_DAP_TAPID -ignore-version -enable + +# declare the 4 main application cores +set _TARGETNAME $_CHIPNAME.cpu +set _smp_command "" + +set $_TARGETNAME.cti(0) 0x80020000 +set $_TARGETNAME.cti(1) 0x80120000 +set $_TARGETNAME.cti(2) 0x80220000 +set $_TARGETNAME.cti(3) 0x80320000 + +set _cores 4 +for { set _core 0 } { $_core < $_cores } { incr _core 1 } { + + set _command "target create ${_TARGETNAME}$_core aarch64 \ + -chain-position $_CHIPNAME.dap -coreid $_core -ctibase [set $_TARGETNAME.cti($_core)]" + + if { $_core != 0 } { + # non-boot core examination may fail + #set _command "$_command -defer-examine" + set _smp_command "$_smp_command ${_TARGETNAME}$_core" + } else { + # uncomment when "hawt" rtos is merged + # set _command "$_command -rtos hawt" + set _smp_command "target smp ${_TARGETNAME}$_core" + } + + eval $_command +} + +eval $_smp_command -- ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ OpenOCD-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/openocd-devel
