ti,cc23x0-ccfg-flash

Vendor: Texas Instruments

Description

This binding describes the TI CC23X0 flash CCFG (custom configuration)
area content.

Notes:
  The flash CCFG sector node (e.g. flash1) should have both
  "ti,cc23x0-ccfg-flash" and the "soc-nv-flash" compatibles.
  The latter is used from mcuboot and other modules to identify
  the flash area.

Properties

Properties not inherited from the base binding file.

Name

Type

Details

ti,bldr-vtor-flash

int

Bootloader entry point when a boot from flash is selected.
Valid range: 0 - 0x0effffff
Default is 0, which is the standard initial configuration.

ti,serial-io-cfg-index

int

Index of which I/O mapping to use for UART/SPI.
Valid range: 0 - 2
Default is 0, which is the standard initial configuration. Other values can be
used depending on I/O availability.

ti,pin-trigger

boolean

If not present, then bootloader unconditionally triggers.
Else normal pin trigger check is performed.

ti,pin-trigger-dio

int

Index of DIO pin to use for pin trigger check.
Valid range: 0 - 25
Default is 0, which is the standard initial configuration. Other values can be
used depending on DIO availability.

ti,pin-trigger-level-hi

boolean

If not present, then the level on trigger pin that triggers bootloader is low.
Else level that triggers bootloader is high.

ti,debug-port

boolean

If not present, then the SWD port is disabled altogether at a certain point in boot
before invoking either bootloader or application.

ti,energy-trace

boolean

Allows using EnergyTrace power analyzer tool.
EnergyTrace software is an energy-based code analysis tool that measures
and displays the energy profile of an application and helps optimize it for
ultra-low-power consumption.

ti,flash-verify

boolean

Determines whether flash verifying SACI commands are allowed. These commands only check
integrity against a provided CRC32 value, never return any flash contents. Flash verify
commands are always allowed after a chip erase and until the first reset after the CCFG
sector has been programmed.

ti,flash-program

boolean

Determines whether flash programming SACI commands are allowed.
Reset to allowed after a chip erase.

ti,chip-erase

boolean

Determines whether chip erasing SACI commands are allowed.

ti,ret-to-factory

boolean

Allows return-to-factory procedure by SACI.
To do full failure analysis including flash, a return to factory procedure is supported.

ti,wr-er-prot-sect0-31

int

Bitmask for write/erase protection of individual sectors in sector range [0, 31].
Controls whether flash programming is allowed through SACI. The same mechanism
controls whether the application is allowed to program these sectors.
0 = protected.
Valid range: 0 - 0xffffffff
Default is 0xffffffff to allow programming these sectors.

Default value: 4294967295

ti,wr-er-prot-sect32-255

int

Bitmask for write/erase protection of groups of 8 sectors, in sector range [32, 255].
Bit i protects sectors [32 + 8i, 39 + 8i].
0 = protected.
Valid range: 0 - 0xffffffff
Default is 0xffffffff to allow programming these sectors.

Default value: 4294967295

ti,wr-er-prot-ccfg-sect

int

Bitmask for write/erase protection of CCFG sectors.
Valid range: 0 - 0xffffffff
Default is 0 to prevent from mistakenly programming these sectors.

ti,wr-er-prot-fcfg-sect

int

Bitmask for write/erase protection of FCFG sectors.
Valid range: 0 - 0xffffffff
Default is 0 to prevent from mistakenly programming these sectors.

ti,wr-er-prot-engr-sect

int

Bitmask for write/erase protection of ENGR sectors.
Valid range: 0 - 0xffffffff
Default is 0 to prevent from mistakenly programming these sectors.

ti,chip-er-retain-sect0-31

int

Bitmask for chip erase protection of individual sectors in sector range [0, 31].
Controls whether a chip erase affects a sector or not. The mechanism is intended
to allow flash sectors devoted to logging or runtime state/configuration to survive
the chip erase during a FW update.
0 = protected.
Valid range: 0 - 0xffffffff
Default is 0 to prevent from mistakenly programming these sectors.

ti,chip-er-retain-sect32-255

int

Bitmask for chip erase protection of groups of 8 sectors, in sector range [32, 255].
Bit i protects sectors [32 + 8i, 39 + 8i].
0 = protected.
Valid range: 0 - 0xffffffff
Default is 0 to prevent from mistakenly programming these sectors.

erase-block-size

int

address alignment required by flash erase operations

write-block-size

int

address alignment required by flash write operations
