Ql_RIL_Initialize() blocks forever when using several tasks

[ASL07]

Hi,

It seems that when using more than one task, Ql_RIL_Initialize() never returns and blocks the task from which it was called forever. I am calling Ql_RIL_Initialize() after MSG_ID_RIL_READY

I have uploaded a repo from which the error can be reproduced here: https://github.com/ASL07/OpenCPURilInitHangMultitask

Please follow instructions on the README

Has anyone experienced anything similar?

@Wiz-IO Reviewing the code in your Arduino port, I see you suspend the Arduino task until RIL is initialize, is taht a workaround for this? Anyway, I tried to replicate what you are doing in my app and I cannot make it work.

Thanks

I am sorry but I am not Quectel FAE...

BTW: your task config is wrong https://github.com/ASL07/OpenCPURilInitHangMultitask/blob/master/config/custom_task_cfg.h#L53

first is the main task next have two reserved tasks for RIL interface... and Ql_RIL_Initialize() block next is user tasks example: https://github.com/Wiz-IO/framework-quectel/blob/master/templates/bc66/arduino_task_cfg.h#L5

Thank you, that was the problem. It isn't mentioned anywhere that the order of tasks has to be strictly this:

TASK_ITEM(proc_main_task,       main_task_id,   10*1024, DEFAULT_VALUE1, DEFAULT_VALUE2)
TASK_ITEM(proc_reserved1,       reserved1_id,    5*1024, DEFAULT_VALUE1, DEFAULT_VALUE2)
TASK_ITEM(proc_reserved2,       reserved2_id,    5*1024, DEFAULT_VALUE1, DEFAULT_VALUE2)

// User tasks must be defined after proc_reserved2
TASK_ITEM(user_task,        user_task_id,    10*1024, DEFAULT_VALUE1, DEFAULT_VALUE2)
