[GitHub] [incubator-nuttx] masayuki2009 opened a new pull request #292:
arch: armv7-a: Fix heap corruption in SMP mode
masayuki2009 opened a new pull request #292: arch: armv7-a: Fix heap corruption in SMP mode
URL: https://github.com/apache/incubator-nuttx/pull/292
### Summary
- Currently up_allocate_heap() assumes that g_idle_topstack points top of the heap memory. However, g_idle_topstack pointed incorrect address in SMP mode which resulted in heap corruption. This PR moves g_idle_topstack at the end of .noinit to avoid this issue.
### Impact
- This PR affects Cortex-A architectures.
### Testing
- I tested sabre-6quad:smp and sabre-6quad:nsh with QEMU.
