From 7517fc3cdf4913727dda1a1cad464927d24db7ec Mon Sep 17 00:00:00 2001 From: Gunar Schorcht Date: Sun, 2 Mar 2025 10:20:04 +0100 Subject: [PATCH 19/28] heap: IRAM is not used as heap RIOT only supports memory as a heap that allows byte access. IRAM only allows word-by-word access. --- components/heap/port/esp32/memory_layout.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/components/heap/port/esp32/memory_layout.c b/components/heap/port/esp32/memory_layout.c index b35d8c1b3e..b6c6d59010 100644 --- a/components/heap/port/esp32/memory_layout.c +++ b/components/heap/port/esp32/memory_layout.c @@ -95,6 +95,7 @@ const soc_memory_region_t soc_memory_regions[] = { { 0x3FFF0000, 0x8000, SOC_MEMORY_TYPE_DIRAM, 0x400A8000,true}, //pool 7 <- can be used for MAC dump { 0x3FFF8000, 0x4000, SOC_MEMORY_TYPE_DIRAM, 0x400A4000,true}, //pool 6 blk 1 <- can be used as trace memory { 0x3FFFC000, 0x4000, SOC_MEMORY_TYPE_DIRAM, 0x400A0000,true}, //pool 6 blk 0 <- can be used as trace memory +#if !defined(RIOT_VERSION) { 0x40070000, 0x8000, SOC_MEMORY_TYPE_IRAM, 0, false}, //pool 0 { 0x40078000, 0x8000, SOC_MEMORY_TYPE_IRAM, 0, false}, //pool 1 { 0x40080000, 0x2000, SOC_MEMORY_TYPE_IRAM, 0, false}, //pool 2-5, mmu page 0 @@ -113,6 +114,7 @@ const soc_memory_region_t soc_memory_regions[] = { { 0x4009A000, 0x2000, SOC_MEMORY_TYPE_IRAM, 0, false}, //pool 2-5, mmu page 13 { 0x4009C000, 0x2000, SOC_MEMORY_TYPE_IRAM, 0, false}, //pool 2-5, mmu page 14 { 0x4009E000, 0x2000, SOC_MEMORY_TYPE_IRAM, 0, false}, //pool 2-5, mmu page 15 +#endif #ifdef CONFIG_ESP_SYSTEM_ALLOW_RTC_FAST_MEM_AS_HEAP { SOC_RTC_DRAM_LOW, 0x2000, SOC_MEMORY_TYPE_RTCRAM, 0, false}, //RTC Fast Memory #endif -- 2.34.1
