ln882x_zero_malloc.c

Go to the documentation of this file.

/*
 * LN882x: heap_5 returns NULL for a zero-size request, and the SDK's
 * malloc-failed hook ends in LN_ASSERT(0), which spins until the watchdog
 * resets the chip. LibreTiny's scan handler asks for zero entries when a scan
 * finds no networks. Linked with -Wl,--wrap=pvPortMalloc so every allocation
 * comes through here; drop it once LibreTiny no longer allocates zero entries.
