Ice & spi ethercat slave code

Hello,

I stored ecat_appl_spi.bin on ice board by using Twincat application, it's ok, the program run correctly in spi flash.

The probleme now, is that if I try to debug with Jtag probe/CCS5 an other project (bigTimeICE or I2C_led), the project is loaded, but it's not possible to debug it.

Is it due to the ecat_appl_spi.bin spi boot code which can not disable ethercat interrupts, a bad mapping ?

I thought that the Jtag probe took the control of all the registers, is it true ?

After, if I store bootSpi.bin by using Twincat, it's ok, it's now possible to load/debug any project step by step.

An idea ?

    Hi Jean,

    could you provide what product, version, and example you're using?

    Hi Tom,

    My config: Seven64, TMDX ICE 3359 hardware, CCS 5.4.0.00091 and SDK am335x_sysbios_ind_sdk_1.1.0.1.

    Today, it's ok, friday I have loaded and ran with success the flashing toolscode: isdk_spi_flasher.out. to re-programm the bootloader boot_spi.bin. It's possible now for me to debug (step by step) the ICE board with the JTag probe.

    But i don't understand why (when botloader not flashed) JTag probe + CCS debug could'nt debug step by step in memory whatever sdk projects examples.

    I thought the Jtag probe + CCS took total control of the ice board regardless the programm flashed, finally, the boot loader is compulsory to debug.

    Thank you for your involvement.

    JM

    Now it's different, ice board was flased with boot loader (boot_SPI.bin Sept/02/2013), if i run ecat_appl with CCS, the communication with TwinCat is ok.

    I try to flash ecat_appl_spi.bin file using Twincat:

    click on <Init> button => current state: Init

    click on <BootStrap> button => current state: Boot

    click on <DownLoad> button => Select <ECATFW__ecat_appl_spi.bin> (generated by CC5 in release mode).

    At the botom of the window, the loading bar grow...

    When it's terminated, I click on <init> button to reset.

    If I switch off /On the supply (wait 10 secunds), the ethercat code is not running, it's the boot block which is running.

    I think that the loading action is ok, but not the flashing, why ????

    Hi,

    Can you share the UART debug messages for this application( Please  capture after firmware download and after power cycle)?
