Target board: DEVKIT, SPC5748GMKU6;
IDE: S32DS for Power Architecture, Version: 2017.R1 Build id: 171018;
Debugger: OpenSDA;

Issue description: I changed the default generated .ld file by extending the user code space:

flash_rchw : org = 0x00F90000, len = 0x4
cpu0_reset_vec : org = 0x00F90000+0x10, len = 0x4
cpu2_reset_vec : org = 0x00F90000+0x04, len = 0x4

m_text : org = 0x00F94000, len = 1328K // My new setting
/*m_text : org = 0x01000000, len = 1024K*/ // Default setting
m_data : org = 0x40000000, len = 192K

Result: right after the changing, the compling and debuging can all work, after stop debugging and re-power the board, the program do not run any more, and I tried to debug again, the board can no longer be connected, and S32DS always poped up:
1. The target may have entered reset escalation. Please power cycle the board.
2. Warning: Device is not detected or may be censored. Please check connections or please enter password in GDB server parameters within debug configurations using the flag -uncensorpassword=n, then restart the debug session.

For more details, pls. check the attached screenshot and .ld file.


Hope for response soon, appreciate.



@Martin Kovar, Hi, just compared with your answer, the flash space starting from 0x00F94000 is applicable, right?

Jiri Kral Hi, I saw your answer Unable to start debug session on MPC5748G board. download stops at 98%   but unfortunately PROGPPCNEXUS seem not downable unless pay for it. Any other solutions?
