From 8671786934eab0d2894809014f99c005f2c8d22a Mon Sep 17 00:00:00 2001 From: Pavel Pisa Date: Thu, 22 Sep 2016 09:50:59 +0200 Subject: arm/tms570: include hardware initialization and selftest based on Ti HalCoGen generated files. The configuration is specific for TMS570LS3137 based HDK. Pins configuration can be easily changed in rtems/c/src/lib/libbsp/arm/tms570/hwinit/init_pinmux.c file. The list tms570_selftest_par_list in the file rtems/c/src/lib/libbsp/arm/tms570/hwinit/bspstarthooks-hwinit.c specifies peripherals which health status is examined by parity self-test at BSP start-up. It can be easily modified for other TMS570 family members variants same as the selection of other tests in bspstarthooks-hwinit.c. --- .../arm/tms570/hwinit/tms570_selftest_parity.h | 110 +++++++++++++++++++++ 1 file changed, 110 insertions(+) create mode 100644 c/src/lib/libbsp/arm/tms570/hwinit/tms570_selftest_parity.h (limited to 'c/src/lib/libbsp/arm/tms570/hwinit/tms570_selftest_parity.h') diff --git a/c/src/lib/libbsp/arm/tms570/hwinit/tms570_selftest_parity.h b/c/src/lib/libbsp/arm/tms570/hwinit/tms570_selftest_parity.h new file mode 100644 index 0000000000..a1c3ec7b3e --- /dev/null +++ b/c/src/lib/libbsp/arm/tms570/hwinit/tms570_selftest_parity.h @@ -0,0 +1,110 @@ +/** + * @file tms570_selftest_parity.h + * + * @ingroup tms570 + * + * @brief Check of module parity based protection logic to work. + */ +/* + * Copyright (c) 2016 Pavel Pisa + * + * Czech Technical University in Prague + * Zikova 1903/4 + * 166 36 Praha 6 + * Czech Republic + * + * The license and distribution terms for this file may be + * found in the file LICENSE in this distribution or at + * http://www.rtems.org/license/LICENSE. + */ + +#ifndef LIBBSP_ARM_TMS570_SELFTEST_PARITY_H +#define LIBBSP_ARM_TMS570_SELFTEST_PARITY_H + +#include + +/** + * The magic number used to switch most of the peripherals + * into parity protection test mode + */ +#define TMS570_SELFTEST_PAR_CR_KEY 0xA + +typedef struct tms570_selftest_par_desc tms570_selftest_par_desc_t; + +typedef void tms570_selftest_par_fnc_t( const tms570_selftest_par_desc_t *desc ); + +/** + * Decriptor specifying registers addresses and values used to test + * that parity protection is working for given hardware + * module/peripheral.
