CYW4390x commands

The CYW4390x chip supports only limited subset of flash-related commands. Currently, the following flash programming commands are supported:

program

Programs a given binary programming into the flash of the target device.

program <filename> [reset] [exit]

The only required parameter is filename; the others are optional.

• reset

  – Calls

  reset run

  (see

  reset [run] [halt] [init]

  for details)

• exit

  – Shuts down OpenOCD

Limitations compared to standard

program

command:

• Only binary files are supported. Files in any format other than binary will be programmed as a binary data. For example, if a HEX file is programmed, the flash will contain textual representation of the file.

• The

  preverify

  ,

  verify

  , and

  offset

  parameters are not supported. Verification is done automatically during programming.

Example:

The next example connects ModusToolbox™ OpenOCD CLI to the CYW9WCD1EVAL1 board with the CYW4390x MCU target, programs the flash with the

firmware.bin

file, resets the target, and finally shuts down the OpenOCD programmer.

openocd -s ../scripts -f board/cyw9wcd1eval1.cfg -c "program d:/firmware.bin reset exit"

Note:

For erasing CYW4390x chip use the

erase_all

command.
