heap_caps_malloc was called but failed to allocate1696byteswith6144capabilities. This may or may not indicate a problem:heap_caps_malloc_prefer(...)may try multiple allocations which may fail until one succeeds. E.g. if PSRAM is preferred but no external RAM is present, the first attempt ...
void* heap_caps_malloc(size_t size, uint64_t capabilities); ``` 参数解释: 1. `size`:要分配的内存块的大小(以字节为单位)。 2. `capabilities`:一个 64 位整数,用于指定分配的内存块的能力。这可以是一个或多个预定义的能力值,例如`CAP_SYS_ADMIN`、`CAP_SYS_RAWIO` 等。这些能力定义了内存块...

We added a piece of code in heap_caps that logs each time a malloc/free is made After multiple retries, we see that the address that is corrupted is touched mainly by MTXON We isolated the logs to MTXON mallocs. Please note that we don't know what other tasks MTXON works with,...
