URL: https://github.com/apache/incubator-nuttx/issues/802
Recently I use qemu to simulate the sabre-6quad board based on the SMP
defconfig .
When turn on CONFIG_DEBUG_FEATURES CONFIG_DEBUG_ERROR options and run
app/testing/smp program , the nuttx system was locked.
See call stack, I found the thread1 was locked at spinlock() and thread2 was
locked at enter_critial_section().
Turn off the CONFIG_DEBUG_ERROR options and the SMP program runs normally.
What could be the problem?
My defconfig is as follows:
