Tool/software: TI-RTOS
Hi
I'm developing custom application EtherCAT function on AM437x IDK 1.4A
After I use TwinCAT 3 write my ESI file into EEPROM, TwinCAT can get the EtherCAT Box of custom application
But when I re-power up AM437x IDK, TwinCAT will get "BOX(TIESC-002)" (Full Feature Demo Application Example)
And I found that EtherCAT API is using EERPOM emulation (volatile EEPROM)
My question is how can I write custom ESI file into SPI Flash by using TwinCAT?
thank you

Hi Paula,
Thanks for your replying
I had tried generating EERPOM binary file into tiesc_eerpom.h
but the program will stuck in do-while loop in HW_init() function (tieschw.c)
u16PdiCtrl will always get 0x05 not 0x80
The program will only successively initialize when using TI's example code of tiesc_eeprom in tiesc_eeprom.h
I check the EtherCAT ESC ET1100 datasheet
PDI Control register(address 0x0140) with value 0x05 means the CPU use SPI to communicate with ESC
I also check SSC ( I use SSC5.11 and "SSC OD Tool.exe" to generate ESI file) configuration
The ESC_EEPROM_EMULATION and ESC_EEPROM_EMULATION has been set
but the ESI file will be same as setting EL9800_HW
How can I get through this problem?
thank you
Yi-Lin
