Hi,

I was trying to do my first program with Freescale Tower (MH60FN1M0VLQ12), but something in the tutorial was wrong and now I have got blinking reset on the board.

Is there any possibility how to repair it?

Thank for your help

Hi,

My suggest for your is create a blank project first, then check if it can download into board. If it cannot be download, please try to use J-Link commander to unlock it. Hope it can help you. Thanks.

Best Regards

Paul

Thank you so much for your answer.

You are right that I´am not able to download the project to the board, codewarior gets 99% of downloading and then it gets stuck.

I just googled J-link commander and found only HW programmer (SEGGER). Is there any possibility to solve it without any other HW and solve it only with the programmer on board?

Hi,

now i´m trying to program the exaple "Hello world" project, it about 7,200 bytes, and the last message in command line is "Initializing..", 99% of downloading and it gets stuck.

I tried the same process on the another board (the same type) and there was everything ok, it was normally programmed.

Best Regards,

Hi,

It looks that MK60FN1M0VLQ12 could be locked.

So, it should be the best if you erase flash using J-Link.

Please, follow these steps: Unlocking and Erasing FLASH with Segger J-Link | Eclipse Zone

I hope this help you,

Hi,

I am trying to erase the device flash with J-link lite, but there is a problem that the MCU is running and the J-link commander can´t halt them.

Don´t you know how to stop (halt) it?..

Best regards,

Hi,

Yes. For that you can use J-link Commander.

With symbol "?" list the table of commands.

or you can go to table (p. 64, 69) at User Guide for J-Link https://www.segger.com/cms/admin/uploads/productDocs/UM08001_JLink.pdf

I hope it helps,
