Resetting the EA LPC4088 QSB
Hi all,
I have recently started using the mBed LPC1768 platform and now migrated to the LPC4088 QSB.
For the 1768, I have been using the following:
extern "C" void mbed_reset(); (Declared at the top of the program)
And then throughout the program, when needed to, I use "mbed_reset();" to reset the program.
I just got my LPC4088 today and was porting my 1768 code over.
I have most of the bugs worked out.
But this is the one things that I cannot fix.
Is there something similar I can use?
Or is there a built-in function that will allow me to reset the 4088 in a similar fashion?
Thank you in advance for your help.

'#define DEVICE_SEMIHOST' indicates whether or not the module has the so-called mbed interface chip. This is the processor used for flashing, USB serial comms to the host, local-filesystems etc. The interface is also used to reset the target processor (eg lpc1768) when you call mbed_reset(). You need another solution when there is no interface chip on your board.

mbed_reset() is defined in the mbed_interface.c into the mbed libs. So from this fonctions is only defined if DEVICE_SEMIHOST if set to 1. this '#define DEVICE_SEMIHOST' is different for each mbed board and is set into he device.h file that deal with each board. It is defined to 1 for the 1768 but to 0 for the 4088 board.
So from we have to find another way to reset the 4088QSB...

Thank you Raph and Wim.
At the very least it confirmed what I was suspecting.
I will try to implement a hardware solution to do the resetting.
Thank you both for your quick replies.
