; @Title: Flash declaration for ST STM32H5 internal flash
; @Description:
; Script arguments:
; DO stm32h5 [PREPAREONLY] [CPU=<cpu>] [DUALPORT=<0|1>]
; PREPAREONLY only declares flash but does not execute flash programming
; CPU=<cpu> selects CPU derivative <cpu>
; DUALPORT=<0|1> use dual port memory access (default 1)
; HOSTMODE=<0|1> use host-mode programming (1) or target-based binary (0)
; Example:
; DO ~~/demo/arm/flash/stm32h5 PREPAREONLY
; Note:
; This file must NOT be modified.
; This file is intended to stay within TRACE32 installation.
; Usage examples are available in the ~~/demo/arm/hardware/... subdirectories.
;
; List of STM32H5 derivatives and their configuration:
; CPU-Type TZ SRAM FLASH
; [byte] [byte]

; STM32H503xB N 0x08800 0x020000
; STM32H562xG Y 0xA1000 0x100000

; STM32H563xI Y 0xA1000 0x200000
; STM32H573xI Y 0xA1000 0x200000
;
; Flash nonsecure : 0x08000000--<end addr>
; Flash secure : 0x0C000000--<end addr> (TZ=Y)
; SRAM nonsecure : 0x20000000--<end addr>
; SRAM secure : 0x30000000--<end addr> (TZ=Y)
; Backup SRAM : 0x40036400--<end addr> (0x50036400 start addr for secure)
;
; NOTE: In case there is an active window watchdog that cannot be disabled using
; the debugger, HOSTMODE=1 will use an alternative programming mode. This is
; slower than a target-based binary for flash operations but will prevent a
; watchdog reset.
;
; Currently, host-mode (1) is the default.
