From 4e9ee81f0c2c4b86ce006206ae9b65e89210e784 Mon Sep 17 00:00:00 2001 From: Andreas Bolsch Date: Mon, 20 Jun 2016 21:02:29 +0200 Subject: Flash handling for STM32F76x/77x and F446 added - added ids for various parts - rewrite of sector allocation to deal with dual-bank F76x/77x - single- / dual-bank mode for F76x/77x - sector protection adapted for F76x/77x in dual-bank mode - handling of additional option bits (28-31) in FLASH_OPTCR in options_read and options_write for F42x/43x/469/479/7xx, options bits 0-1 masked out - check for sensible value of user_options in options_write - some #defines clarified, non-needed ones removed - docs updated (options read, options write) Change-Id: Ie4db80e60baa7d2663e024ab1f278640b1ce901b Signed-off-by: Andreas Bolsch Reviewed-on: http://openocd.zylin.com/3526 Tested-by: jenkins Reviewed-by: Andreas Fritiofson --- doc/openocd.texi | 17 +++++++++++++++-- 1 file changed, 15 insertions(+), 2 deletions(-) (limited to 'doc') diff --git a/doc/openocd.texi b/doc/openocd.texi index 983ce3ca..dcb843ac 100644 --- a/doc/openocd.texi +++ b/doc/openocd.texi @@ -5827,8 +5827,8 @@ The @var{num} parameter is a value shown by @command{flash banks}. @end deffn @deffn {Flash Driver} stm32f2x -All members of the STM32F2 and STM32F4 microcontroller families from ST Microelectronics -include internal flash and use ARM Cortex-M3/M4 cores. +All members of the STM32F2, STM32F4 and STM32F7 microcontroller families from ST Microelectronics +include internal flash and use ARM Cortex-M3/M4/M7 cores.
