ESP32-S2使用外部PSRAM，使用超过16K后，写入后再读出数据对不上的原因？

问答对人有帮助，内容完整，我也想知道答案 0 Code: Select all uint32_t i = 0 ; ESP_LOGI(TAG,"free size (psram):%d",heap_caps_get_free_size(MALLOC_CAP_SPIRAM)); uint8_t * tbuf = (uint8_t)heap_caps_malloc( 321024 , MALLOC_CAP_SPIRAM \| MALLOC_CAP_32BIT ); ESP_LOGI(TAG,"addr[%x]",(uint32_t)tbuf); ESP_LOGI(TAG,"free size (psram):%d",heap_caps_get_free_size(MALLOC_CAP_SPIRAM)); for(i=0 ; i < 32*1024 ; i++) { tbuf = 0 ; } show_hex(tbuf,256); PS D:202203ESP32ESP32-S3blink> C:Usershyj.espressifpython_envidf4.4_py3.8_envScriptspython.exe C:Usershyjespesp-idftoolsidf.py -p COM98 monitor Executing action: monitor Running idf_monitor in directory d:202203esp32esp32-s3blink Executing "C:Usershyj.espressifpython_envidf4.4_py3.8_envScriptspython.exe C:Usershyjespesp-idftools/idf_monitor.py -p COM98 -b 115200 --toolchain-prefix xtensa-esp32s3-elf- --target esp32s3 d:202203esp32esp32-s3blinkbuildblink.elf -m 'C:Usershyj.espressifpython_envidf4.4_py3.8_envScriptspython.exe' 'C:Usershyjespesp-idftoolsidf.py' '-p' 'COM98'"... --- WARNING: GDB cannot open serial ports accessed as COMx --- Using \.COM98 instead... --- idf_monitor on \.COM98 115200 --- --- Quit: Ctrl+] \| Menu: Ctrl+T \| Help: Ctrl+T followed by Ctrl+H --- ESP-ROM:esp32s2-rc4-20191025 Build:Oct 25 2019 rst:0x1 (POWERON),boot:0x8 (SPI_FAST_FLASH_BOOT) SPIWP:0xee mode:DIO, clock div:1 load:0x3ffe6100,len:0x176c load:0x4004c000,len:0xa48 load:0x40050000,len:0x2e48 SHA-256 comparison failed: Calculated: 67ba66aac9d3b0847048c39f9d2dce93a10a30f43a9fce62292c438cecd9d47e Expected: c47b10cf00b4932fac9990c607467c8b94c15be45c18b3dd1fc8b512a5c4126b Attempting to boot anyway... entry 0x4004c204 I (40) boot: ESP-IDF v4.4-dirty 2nd stage bootloader I (40) boot: compile time 10:55:31 I (40) boot: chip revision: 0 I (43) boot.esp32s2: SPI Speed : 80MHz I (47) boot.esp32s2: SPI Mode : DIO I (52) boot.esp32s2: SPI Flash Size : 4MB I (57) boot: Enabling RNG early entropy source...
