Hi I downloaded the latest release, 7.3.0, and while trying to work with the LPC1114 example for the LPCXpresso toolchain, my little application hanged at the SVC_Handler handler interrupt. After digging into the source code I found that changing this line

#define vPortSVCHandler SVCall_Handler

for this other one

#define vPortSVCHandler SVC_Handler

(FreeRTOSConfig.h, line 143) make my application to run nicely and smoothly. Is that a bug? Greetings!!

No, it comes about because CodeRed did not have the correct CMSIS names for their default handlers, so the names in their default vector tables was different. SVC_Handler is the standard name, so it looks like CodeRed have changed their code. Regards.

I got it!! So the example was written when the default’s handler names were different. Then, later on, CodeRed changed their names to the standard ones? This is a short list of interrupt handler names that are found in **cr_startup_lpc12xx.c **(LPCXpresso 5.0.10)
