LS1043ARDB-PD preboot issue

TJAhn — Wed, 24 Jan 2024 12:14:39 GMT

Hello,

I am struggling with some problems with LS1043ARDB-PD.

I did some preboots to execute "help" command in teraterm with connection in this Evaluation Board.

And I followed getting started guide to this.

But while i was using this board, i had changed k22fx512_if_mbed.bin file's connection properties into notepad++ file, because of curiosity.

But now the board won't get to the preboot even i follow steps even thought i reset the connection properties.

How can i solve this case?

Hello, Please follow the steps below:

Plug in power to LS board. Hold down Reset button while plugging the PC USB cable into the CSAM USB connector on the board.
On Windows, the board will be mapped as a Mass Storage Device under a volume labelled 'BOOTLOADER'.
LED for MBED status will blink in green on the board to acknowledge it is in bootloader mode.

1. Copy the attached binary into the 'BOOTLOADER’
2. Wait the binary copy to finish; LED for MBED status will blink with higher rate on finish;
3. Unplug the USB cable from the board, then plug it back in to power cycle the module
4. The board should be ready to connect to CodeWarrior

Also, there is a known issue with MBED operation under Win10.

This is the work around we have confirmed to fix the mbed issue on Win10 PC's:
- Go to the "Start" option on the PC and type the command "Services"
- Than you should see the following "Services" window open
- Select the "Storage Services" and on the left-hand side of the window click the "Stop the service"
