opencpu undefined reference to _sbrk #22

Closed ASL07 closed 4 years ago

It seems that syscalls.c is not being linked This is the error I am getting. I am not using dynamic memory allocation

I have seen a fix here https://github.com/svaarala/duktape/issues/1941 that consists on adding this to a source file:

void *_sbrk(s32 inc)
{
    APP_DEBUG("_sbrk called.\r\n");
    while(1);
    return NULL;
}

however there must be a better solution.

Please let me know, Thanks

you use old PLATFORM: Quectel 2.0.14 there is new Version: 2.1.01 https://github.com/Wiz-IO/platform-quectel#quectel-development-platform-for-platformio

sbrk included in project https://github.com/Wiz-IO/platformio-quectel-examples/blob/master/BC66_SDK/CPP/BC66_CPP_HELLO/config/custom_sys_cfg.c#L36

I have updated the platform to the latest. The are several issues:

  1. URC_SOCKET_RCV_DATA is not defined anymore src/as_main.c:193:14: error: 'URC_SOCKET_RECV_DATA' undeclared (first use in this function); did you mean 'URC_SOCKET_CLOSE'?

  2. It seems that the app is not loading. I have programmed the example_gpio.c and I get no output in the usb serial port. And also the Led doesn't change state. I have this in my custom_sys_cfg.h

    static const ST_AppEnable appEnableCfg = {
APP_ENABLE
};

  3. Weird compilation warnings about non unicode characters on these files

ah... just read the wiki https://github.com/Wiz-IO/platform-quectel/wiki/SDK-BC66#opencpu

By default some RIL functions is disabled, see your project/custom_feature_def.h

ASL07 commented 4 years ago

I was compiling this project with the previous version of the platform, and the app was running fine. Once I upgraded to the latest version, then I started getting this errors. I have not touched my custom_feature_def.h, so that should not be the problem

Here is the content of custom_feature_def.h just in case

#ifndef __CUSTOM_FEATURE_DEF_H__
#define __CUSTOM_FEATURE_DEF_H__

/************************************************************************
 * RIL Function on/off
 ************************************************************************/
#define __OCPU_RIL_SUPPORT__
#define __OCPU_RIL_SOCKET_SUPPORT__

// #define __OCPU_RIL_LWM2M_SUPPORT__
// #define __OCPU_RIL_MQTT_SUPPORT__
// #define __OCPU_RIL_DFOTA_SUPPORT__

#endif  //__CUSTOM_FEATURE_DEF_H__
Wiz-IO commented 4 years ago

uncomment

define __OCPU_RIL_LWM2M_SUPPORT__

define __OCPU_RIL_MQTT_SUPPORT__

define __OCPU_RIL_DFOTA_SUPPORT__

ASL07 commented 4 years ago

I've already done it and it doesn't make any difference. Why should I uncomment them? I don't need support for those

Wiz-IO commented 4 years ago

your example is from old OpenCPU SDK new OpenCPU v1.5 not use URC_SOCKET_RECV_DATA

there is new Quectel examples https://github.com/Wiz-IO/platformio-quectel-examples/tree/master/BC66_SDK/OpenCPU

ASL07 commented 4 years ago

I get this problem when programming the new example

It seems that the app is not loading. I have programmed the example_gpio.c and I get no output in the usb serial port. And also the Led doesn't change state.

This other problem unrelated to the previous one. I get this everytime I try to use URC_SOCKET_RECV_DATA. I have checked the new tcp exampe, so I should be using Ql_Socket_Recv_Register() instead in the new SDK?

URC_SOCKET_RCV_DATA is not defined anymore src/as_main.c:193:14: error: 'URC_SOCKET_RECV_DATA' undeclared (first use in this function); did you mean 'URC_SOCKET_CLOSE'?

Thanks

Wiz-IO commented 4 years ago

are you read me? URC_SOCKET_RECV_DATA is not used in OpenCPU v1.5

Wiz-IO commented 4 years ago

old OpenCPU not have API for sockets and use RIL ( AT commands ) for this New v1.5 have API ( direct call to lwip core functions ) explore https://github.com/Wiz-IO/framework-quectel/blob/master/opencpu/bc66/SDK15/include/ql_socket.h

or ask Quectel: WHY? I just follow OpenCPU SDK

ASL07 commented 4 years ago

Thank you for the clarification

Please, understand that most of us don't have access to the OpenCPU documentation and Quectel does not provide support for OpenCPU unless you place a really big order... It is difficult for us to determine what the changes are from version to version without having access to a changelog

Do you have any idea regarding what can be causing the application not to load? Regards

Wiz-IO commented 4 years ago

Hi, I not have Quectel support too... email me

Wiz-IO commented 4 years ago

btw: update your module with last firmware BC66NBR01A10

Wiz-IO commented 4 years ago

I test platform with original Quectel board and Olimex board and with last two firmwares BC66NBR01A07 and BC66NBR01A10 yesterday I update my Olimex to BC66NBR01A10 and make some tests I can not see problems with uploading btw: BC66 uploader script not have changes

ASL07 commented 4 years ago

I have upgraded the FW to BC66NBR01A10 now it works. That was the problem Thanks
