Hi Team,
Our customer faced ipc_start failed:4 message sometimes as below.
Ipc_start()
LAD_connect: PID = 626, fifoName = /tmp/LAD/626
fopen(responseFIFOName) Error
Ipc_start: LAD_connect() failed: 4
And they tried to change permissions based on http://processors.wiki.ti.com/index.php/IPC_3.x_FAQ#Linux_Ipc_start.28.29_Failures.
But issue is not fixed. So they tried to insert sleep(100) after executing LAD driver. This issue did not happen currently.
IPC version is 3.23.00.01 with VIS: v1.50.12.02 .
I think somtimes LAD_driver wake up is later than RadioApp.exe.
Should we wait executing RadioApp.exe until wake up LAD_driver?
Could you give me any idea to wait LAD_driver wake up instead of sleep?
Best regards,
Ito
