Hi all,

maybe a stupid question: is it possible to replace EtherCAT PRU-ICSS sync task stack sizes (1152 bytes) by

a value with power of 2 (e.g. 2048 bytes) ?

Regards, Thomas

    FYI, I refer to the content of file tiescutils.c located at .\ti\PRU-ICSS-EtherCAT_Slave_01.00.07.02\protocols\ethercat_slave\ecat_appl\EcatStack.

    There is also a stacksize for LEDtask with 1512 bytes. Are there any dependencies or limitations causing these value settings?

    Thomas,

    You can increase the stack size as long as there is enough memory. The reason to set the smaller stack size is mainly for SoC with DDR-less EtherCAT application like AMIC110 with limited on-chip memory, which is not the case for AM437x.
