reset reason is always 6 (external reset) even on power on
Posted: Sun May 28, 2017 5:29 am
Help,
using this trivial program to read the reset reason:
BUT even on power on where I should get 4 as a reset reason I get 6.
I don't think that this is a HW problem since when flashing the nodemcu firmware I get the correct reset reason.
Testet with esp8266 Arduino and 2.4.rc1 and even the branch with the SDK version 2.1.0...
Any ideas welcome
please help

using this trivial program to read the reset reason:
Code: Select all
#ifdef ESP8266
extern "C" {
#include "user_interface.h"
// this is in rom so we have to provide only prototype
// 2, 3 = reset (module dependent?), 4 = wdt
int rtc_get_reset_reason(void);
}
#endif
rst_info *myResetInfo;
int rtc_get_reset_reason(void);
int rtcResetReason = 0;
void setup() {
// put your setup code here, to run once:
//Serial.begin(74880); // just to match the bootloader !!! so we can read it ...
Serial.begin(115200);
// es gibt 2 reset reasons rtc und system NUR system ist richtig...
rtcResetReason = rtc_get_reset_reason();
// myResetInfo = ESP.getResetInfoPtr();
myResetInfo = system_get_rst_info();
}
void loop() {
delay(1000); // slow down so we really can see the reason!!
Serial.printf("myResetInfo->reason %x (hex since uint32) rtcResetReason %d (d)\n",
myResetInfo->reason,
rtcResetReason); // reason is uint32
}
BUT even on power on where I should get 4 as a reset reason I get 6.
