Can I use custom ESI for TMDXICE3359?

Hi, 

I am using TMDXICE3359 and running custom ethercat motion source(cia402 profile) based on sys/bios sdk example.

I used to use "Append box" menu to add box in twincat device list, but this isn't convenient.

I read this article to implement "Scan box" feature in use TwinCAT.
http://processors.wiki.ti.com/index.php/AM335x_SYSBIOS_Industrial_SDK_01.00.00.05_User_Guide#Generating_ESI_Header_file_From_ESI_xml

I used bin2header.exe to convert an ESI binary file to header file.

Then I replaced tiesc_eeprom.h and rebuild project.

But when I clicked "Scan box", TwinCAT can't read PDO and ECAT Statemachine can't reach OP State..

My question is modified tiesc_eeprom.h is avaliable or not??

sorry for my english.

thankyou
