[OOB 5.5] HEXIWEAR + ESP8266 - CMIS-RTOS error

[mray190]

Details

HEXIWEAR with ESP8266 module fails with the following logs. Additionally, had to make the following changes to the generic mbed-os-example-wifi repository:

mbed_app.json

"target_overrides": {
    ...
    "HEXIWEAR": {
        "wifi-tx": "PTD3",
        "wifi-rx": "PTD2"
    }
}

main.cpp

// #if TARGET_UBLOX_EVK_ODIN_W2
// #include "OdinWiFiInterface.h"
// OdinWiFiInterface wifi;

// #else
// #if !TARGET_FF_ARDUINO
// #error [NOT_SUPPORTED] Only Arduino form factor devices are supported at this time
// #endif
#include "ESP8266Interface.h"

ESP8266Interface wifi(MBED_CONF_APP_WIFI_TX, MBED_CONF_APP_WIFI_RX);

// #endif

Reasoning for the above change: The ESP8266 module I used was the HEXIWEAR ESP8266 module and therefore could run on a non-Arduino form factor.

@bulislaw .. bump!

cc @geky please have a look at this

I saw this pop up on a K64F with GCC_ARM using the iotlab network just now as well running this example. Reran and it did not show up, appeared again on a third run so seems somewhat common.

Running with mbed-os commit f31ea0123

mbed OS version: 92fbf2a9b3988d430482fc25a6077f2462e2a634

While trying to reproduce above issue, I got new error:
''' Semaphore 20001ac8 error -17 '''
RtxSemaphore release reaches its max count.

@deepikabhavnani Does #4560 actually fix this issue ?

[adbridge]

Also if this an mbed-os issue rather than a specific issue with the example then this should be raised in mbed-os ?

[ashok-rao]

@mray19027 , can you please move this issue to mbed OS repo? Looks like the mbed_app.json changes you made are platform specific so that can be picked up here and the other CMSIS error needs to go into mbed-os ..

[deepikabhavnani]

@adbridge - #4560 resolves this issue. I will raise issue in mbed-os. How can i remove reference of PR from this issue?

[adbridge]

@deepikabhavnani just delete the comment in your PR will do it :)

Closing. Please reopen if it's still a problem.
