Isp mode from user code

[gfa]

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.

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.
