Isp mode from user code

gfa — Wed, 31 Aug 2016 13:24:13 GMT

Dear All,

I'm using a LPC11C24 (with integrated CAN bus transceiver) and I need to write a function to go to CAN ISP mode from my user code.

Is this possible and how ?

Thanks

Hi Guillaume FANJAS,

The integrated ISP doesn't support the CAN interface.

In my opinion, you need to create a CAN bootloader for the implementation and you can refer to the attachment about the bootlaoder design.
Have a great day,

Thank you for your message,
But for sure ISP is supported by CAN in the LPC11C24, I did software download many times with Flash magic tool (free).

Unfortunately, the only way I know to set the lpc in ISP mode is by a hardware reset while I need to do it by CAN (by user code).
Best regards

Hi Guillaume FANJAS,

Yes, the LPC11C24 supports the UART ISP and CAN ISP routines.

Sorry, I miss the information.

You can use the IAR command to force the LPC11C24 enter into the ISP mode.

Have a great day,
