hello,
I am using lpc xpresso (LPC1114) I have two test boards, and both were working fine. and then I use one of my debug board (recently solder) to burn program in them..
and ow Then I am facing a very rare problem,,,

When I burn Program I2C or SPI (ssp), I am getting clock on port P0.10,,., I don't understand what wrong with it.,.

In i2c program , the clock should be on, SCL.,. nut instead of this the clock is generating on P0.10 :(

Also in SSP the clock is coming from P0.10
Plz help. Is there any hardware setting changed?? I really dont understand :(:(

Default function (see IOCON_SWCLK_PIO0_10 register) for PIO0_10 is SWCLK :p:p

That's your Debug Connection (SWD) Clock ;)

No :(
sorry for my grammar

after the program is burned from my new LPC-Link, there is no clock on SCL for I2C and SCK for SSP.
but before burning from other LPC-Link both examples LPC1114 SSP and I2C worked.

But now examples are working... Blinky,uart,adc still working but no SPI and I2C why,.,,
