我在esp8266（我有一个esp12e）的RTOS固件上遇到了问题，在刷写固件后，从串口读取时，它会一直停留在以下这些行：
ets Jan 8 2013,rst cause:2, boot mode:(3,0)
load 0x40100000, len 31584, room 16
tail 0
chksum 0x24
load 0x3ffe8000, len 944, room 8
tail 8
chksum 0x9e
load 0x3ffe83b0, len 1080, room 0
tail 8
chksum 0x60
csum 0x60
现在我将解释一下我的硬件设置：
GPIO15 -> Gnd
EN -> Vcc
GPIO0 -> Gnd (when flashing)
GPIO0 -> Vcc (normal mode)
对于工具链，我遵循了这个教程，它运行良好： http://microcontrollerkits.blogspot.it/2015/12/esp8266-eclipse-development.html 然后我开始做我的RTOS闪烁示例，我在此发布我的user_main.c代码：
#include "esp_common.h"
#include "gpio.h"
void task2(void *pvParameters)
{
printf("Hello, welcome to client!\r\n");
while(1)
{
// Delay and turn on
vTaskDelay (300/portTICK_RATE_MS);
GPIO_OUTPUT_SET (5, 1);
// Delay and LED off
vTaskDelay (300/portTICK_RATE_MS);
GPIO_OUTPUT_SET (5, 0);
}
}
/******************************************************************************

* We add this function to force users to set rf cal sector, since
* we don't know which sector is free in user's application.
* sector map for last several sectors : ABCCC
* A : rf cal
* B : rf init data
* C : sdk parameters
* Parameters : none
* Returns : rf cal sector

uint32 user_rf_cal_sector_set(void)
{
flash_size_map size_map = system_get_flash_size_map();
uint32 rf_cal_sec = 0;
switch (size_map) {
case FLASH_SIZE_4M_MAP_256_256:
rf_cal_sec = 128 - 5;
break;
case FLASH_SIZE_8M_MAP_512_512:
rf_cal_sec = 256 - 5;
break;
case FLASH_SIZE_16M_MAP_512_512:
case FLASH_SIZE_16M_MAP_1024_1024:
rf_cal_sec = 512 - 5;
break;
case FLASH_SIZE_32M_MAP_512_512:
case FLASH_SIZE_32M_MAP_1024_1024:
rf_cal_sec = 1024 - 5;
break;
default:
rf_cal_sec = 0;
break;
}
return rf_cal_sec;
}
/******************************************************************************
* FunctionName : user_init
* Description : entry of user application, init user function here
* Parameters : none
* Returns : none
*******************************************************************************/
void user_init(void)
{
uart_init_new();
printf("SDK version:%s\n", system_get_sdk_version());
// Config pin as GPIO5
PIN_FUNC_SELECT (PERIPHS_IO_MUX_GPIO5_U, FUNC_GPIO5);
xTaskCreate(task2, "tsk2", 256, NULL, 2, NULL);
}
我也发布了flash命令，第一次执行一次，第二次每次修改代码时执行：
c:/Espressif/utils/ESP8266/esptool.exe -p COM3 write_flash -ff 40m -fm qio -fs 32m 0x3FC000 c:/Espressif/ESP8266_RTOS_SDK/bin/esp_init_data_default.bin 0x3FE000 c:/Espressif/ESP8266_RTOS_SDK/bin/blank.bin 0x7E000 c:/Espressif/ESP8266_RTOS_SDK/bin/blank.bin
c:/Espressif/utils/ESP8266/esptool.exe -p COM3 -b 256000 write_flash -ff 40m -fm qio -fs 32m 0x00000 firmware/eagle.flash.bin 0x40000 firmware/eagle.irom0text.bin
有什么问题吗？我真的不明白为什么它不起作用。当我尝试非OS的示例时，它们运行得非常好。
