LOADFW

Description

This command can be used to tranfer a new firmware image from mass storage card into Flash memory which can then be used to re-program the MCU. The command needs one or two arguments. The first argument is the file name (complete path) of a firmware image that resides on the media. The second argument is an optional argument for internal use only. It can be MV1 or MV2. If the second argument is given, certain parts of the firmware can be changed without affecting the main code.

Parameters

1. File name of the new firmware

2. (Optional) MV1 or MV2, not intended for customer use. Please do not use!

Return Values

ERR_OK (0) if image is transferred successfully into Flash memory.
ERR_TOO_MUCH (31) if image file is too big.
ERR_FR_NOT_READY(13) .... ERR_FS_UNKNOWN(25) file system error if something's gone wrong during access of the file

Example

LOADFW v3_32.bin 

Loads the file v3_32.bin into Flash memory for later re-programming of the MCU

Remarks

Never invoke PROGFW if LOADFW fails. Otherwise the module might be seriously damaged!
