[BLE Mesh]IRAM0 segment data does not fit (IDFGH-2248)

isDerek commented 5 years ago

Environment

Development Kit: [ESP32-Wrover-Kit]
Kit version (for WroverKit/PicoKit/DevKitC): [v1|v2|v3|v4]
Module or chip used: [ESP32-WROVER-B]
IDF version (run git describe --tags to find it): // v4.1-dev-1086-g93a8603c5
Build System: [Make]
Compiler version (run xtensa-esp32-elf-gcc --version to find it): // xtensa-esp32-elf-gcc (crosstool-NG esp32-2019r1) 8.2.0
Operating System: [macOS]
Power Supply: [USB]

Problem Description

init the PSRAM

ESP32-specific --> Support for external,SPI-connected RAM --> Try to allocate memories of Wifi and LWIP...
Bluetooth --> Bluedriod Enable --> BT/BLE will first malloc the memory from the PSRAM
Bluetooth --> Bluedriod Enable --> Use dynamic memory allocation in BT/BLE stack.
Bluetooth --> Blutooth controller --> BLE full scan feature supported.

Expected Behavior

success

Hi @isDerek, could you please elaborate on the problem description? Just "init the PSRAM" and some seemingly menuconfig settings are a bit vague. It would as well be helpful to describe what you're trying to achieve, including an example of your code which has this issue. Thanks.

i want to add the ble mesh module to my wifi demo(the demo is a wifi agent for our company's cloud). when i never change the sdkconfig ( ble & wifi coexist sdkconfig), the log tell me

I (985) wifi: wifi firmware version: a44d1c6
I (986) wifi: config NVS flash: enabled
I (986) wifi: config nano formating: disabled
I (987) wifi: Init dynamic tx buffer num: 32
I (997) wifi: Init data frame dynamic rx buffer num: 64
I (998) wifi: Init management frame dynamic rx buffer num: 64
I (1009) wifi: Init management short buffer num: 32
I (1009) wifi: Init static tx buffer num: 16
I (1010) wifi: Init static rx buffer size: 1600
W (1021) wifi: malloc buffer fail
I (1022) wifi: Init static rx buffer num: 14
I (1022) wifi: Init dynamic rx buffer num: 64
E (1033) wifi: Expected to init 16 rx buffer, actual is 14
I (1033) wifi: Deinit lldesc rx mblock:0
I (1034) wifi: Deinit lldesc rx mblock:0
I (1045) wifi: Deinit lldesc rx mblock:0
I (1045) wifi: Deinit lldesc rx mblock:0

so i think maybe i need init the PSRAM, when i modify the menuconfig, the log occured

region `iram0_0_seg' overflowed by 21116 bytes

iram is instruction ram and unrelated to psram which is a type of data ram. This means too much code is placed in iram.

isDerek commented 5 years ago

oh~ how could i trace the iram space, have some methods?

isDerek commented 5 years ago

i modify the esp32.ld file, i change the iram0_0_seg size from 0x20000 to 0x30000

 iram0_0_seg (RX) :                 org = 0x40080000, len = 0x30000

is it the forbidden behavior? the code can't run completely, the code run stopped

You can't just change iram length because it will overlap with other memory regions that are in use

isDerek commented 5 years ago

could i decrease the size (bt) in the iram0_0_seg ? menuconfig?

isDerek commented 5 years ago

i cancel the WiFi IRAM speed optimization and WiFi RX IRAM speed optimization（menuconfig）. finally, the iram size could be accepted.
