- Sat Aug 22, 2015 4:38 pm #26818 Hi guys,

I need the info of rst_info.reason but am not fit enough to get the struct thingie right

would really appreciate a relevant snippet of code.

that is how far I get:

Code: Select allvoid setup() {
  rst_info *xyz;
  Serial.begin(115200);
  xyz = ESP.getResetInfoPtr();
  Serial.println((*xyz).reason);


and I get this error:

Code: Select allmy_am2321.ino: In function 'void setup()':
my_am2321.ino:42:24: error: invalid use of incomplete type 'struct rst_info'

- Sat Aug 22, 2015 5:48 pm #26826 You've probably forgot some include at the top of your sketch, because it is compiling/running fine for me without any problem.
Otherwise, maybe you have multiple SDKs in your ArduinoIDE installation.

- Sun Aug 23, 2015 6:54 am #26861 Hi,
could you show your includes? I am on staging 1044 version with only one sdk installation (1.20.0-26-gb404fb9-2)
I tried user_interface.h but it doesn't really help ... now defaulted to define the struct myself but not yet checked if it is working (compiled ok) ...

Code: Select allstruct rst_info{
   uint32 reason;
   uint32 exccause;
   uint32 epc1;
   uint32 epc2;
   uint32 epc3;
   uint32 excvaddr;
   uint32 depc;
};
void setup() {
  rst_info *xyz;
  Serial.begin(115200);
  xyz = ESP.getResetInfoPtr();
  Serial.println((*xyz).reason);
}

void loop() {
  // put your main code here, to run repeatedly:

}

tnx,
schufti

- Sun Aug 23, 2015 8:58 am #26862 I struggled, a bit to figure out, since I had some indirect includes ...
But I figured out :

Code: Select all#include <Arduino.h>
extern "C" {
#include <user_interface.h>
}


In my case, is was indirectly included by the IRremote.h ...
