From ae5f878d6acadabaa671a7a30b87e16eb1d718a7 Mon Sep 17 00:00:00 2001 From: Megan Wachs Date: Wed, 30 Nov 2016 10:55:18 -0800 Subject: Bump Everything to Match new Freedom Repo (#8) * Bump tool versions * Use version of OpenOCD which can load programs into flash * Bump OpenOCD to Handle ISSI Flash Programming * Update Header files * add initial support for hifive1 * add dhrystone * add clock helper functions * add openocd cfg file * Demo_GPIO checkpoint -- compiles and runs but no blinky LEDs * Remove riscv-tests submodule * Remove FPGA files, as they are no longer relevant to this Repository * Add openocd_upload script * Add Pinmux Mappings Adding the pinmux mappings to the Platform Header * Add IOF Mappings to platform header * Re-order the IOF Mapping declarations * Add more useful things to platform headers * Get GPIO Demo working again (except interrupts aren't working) * Update README with more OS packages needed A bare ubuntu-16.04.1-server installation could not run `make tools` without these packages. * bump openocd to get SCKDIV fix * Remove duplicated help text for run_debug target * Add package to README that is needed for openocd build Without this package I was seeing two different failures like below when running `make tools`. /home/scottj/freedom-e-sdk/openocd/configure: line 4533: syntax error near unexpected token `0.23' /home/scottj/freedom-e-sdk/openocd/configure: line 4533: `PKG_PROG_PKG_CONFIG(0.23)' Makefile:70: recipe for target '/home/scottj/freedom-e-sdk/toolchain/bin/openocd' failed make: *** [/home/scottj/freedom-e-sdk/toolchain/bin/openocd] Error 2 ... or ... + autoconf configure.ac:12: error: possibly undefined macro: AC_MSG_WARN If this token and others are legitimate, please use m4_pattern_allow.
