Hello Team,

We have two evaluation devices of TC39.
1. With Emulation Device
2. With PD

When we flash the soaftware using Pls debugger to boards, only one is starting up automatically after POWER OFF -> ON transition - Only the ED Triboard.

The second board can be started only if a debugger is connected. Could you please let me know what needs to changed to start automatiocally after POWER OFF -> ON

We are using iLLD Drivers as base for our development and we are using HighTec and same SSW from Infineon.

Regards,

Can you confirm that you have programmed the UCB_BMHDx_ORIG and UCB_BMHDx_COPY on the PD device?

If these are not programmed the debugger will usually set the start address according to your elf file.

A Boot Mode Header is an information structure that specifies user startup options, including the starting address of user code.
In AURIX™ TC3xx Platform, four sets of Boot Mode Headers (BMHDx for x=0, 1, 2, 3) are defined in the User Configuration Blocks (UCB) of Data Flash (DFLASH). Each set contains an original and copy in UCB_BMHDx_ORIG and UCB_BMHDx_COPY, respectively.
