From a177831c46a7e217fed6562510e12183377053f7 Mon Sep 17 00:00:00 2001 From: Thorsten von Eicken Date: Sat, 28 Mar 2020 23:00:06 -0700 Subject: esp32/modesp32: Add idf_heap_info(capabilities) to esp32 module. This commit adds an idf_heap_info(capabilities) method to the esp32 module which returns info about the ESP-IDF heaps. It's useful to get a bit of a picture of what's going on when code fails because ESP-IDF can't allocate memory anymore. Includes documentation and a test. --- tests/esp32/esp32_idf_heap_info.py | 33 +++++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+) create mode 100644 tests/esp32/esp32_idf_heap_info.py (limited to 'tests/esp32/esp32_idf_heap_info.py') diff --git a/tests/esp32/esp32_idf_heap_info.py b/tests/esp32/esp32_idf_heap_info.py new file mode 100644 index 0000000000..f141ae07b5 --- /dev/null +++ b/tests/esp32/esp32_idf_heap_info.py @@ -0,0 +1,33 @@ +# Test the esp32's esp32.idf_heap_info to return sane data +try: + import esp32 +except ImportError: + print("SKIP") + raise SystemExit + +# region tuple is: (size, free, largest free, min free) +# we check that each region's size is > 0 and that the free amounts are smaller than the size +def chk_heap(kind, regions): + chk = [True, True, True, True] + for r in regions: + chk = [ + chk[0] and r[0] > 0, + chk[1] and r[1] <= r[0], + chk[2] and r[2] <= r[0], + chk[3] and r[3] <= r[0], + ] + print(kind, chk) + + +# try getting heap regions +regions = esp32.idf_heap_info(esp32.HEAP_DATA) +print("HEAP_DATA >2:", len(regions) > 2) +chk_heap("HEAP_DATA", regions) + +# try getting code regions +regions = esp32.idf_heap_info(esp32.HEAP_EXEC) +print("HEAP_EXEC >2:", len(regions) > 2) +chk_heap("HEAP_EXEC", regions) + +# try invalid param +print(esp32.idf_heap_info(-1)) -- cgit v1.2.3
