donghengqaz opened a new pull request #2474:
URL: https://github.com/apache/incubator-nuttx/pull/2474


   ## Summary
   
   Optimize IRAM usage based on esp-idf.
   
   From https://github.com/espressif/esp-idf/blob/master/components/esp_wifi/linker.lf & https://github.com/espressif/esp-idf/blob/master/components/esp32/ld/esp32_fragments.lf, we can know following data/text should be placed into IRAM instead of SPI Flash:
   
   - libphy.a (RODATA)
   - librtc.a (TEXT)
   - libpp.a (wifi_iram)
   
   ## Impact
   
   Decrease about 87KB IRAM space from Wi-Fi related libs.
   
   ## Testing
   
   Using Iperf to test.
