S32K311 Flash Erase/Program Failure with Sector Lock

[sochoi]

Hello,

I am currently developing based on the S32K311, and the HSE Firmware has already been downloaded. I have a few questions related to the Flash Lock issue and would like to ask for your confirmation.

■ Question
1. Despite never manually writing any DCF records or lock-related settings in the UTEST area, a "Sector is locked" error occurs during Flash programming.
→ Could you please confirm if there are any conditions under which the system can automatically apply a Sector Lock?

2. If the Sector Lock is indeed applied, please let me know if there is a method to unlock it.
→For example: Performing a Mass Erase, etc.

■ Development Environment:

• MCU: S32K311
• Debug Probe: SEGGER J-Link Pro (Firmware V5.1)
• Connection: SWD @ 4000 kHz
• Tools Used:
  • SEGGER J-Flash v8.46
  • IDE: S32 Design Studio 3.5

1. GDB erase failure: Sector is locked

2. J-Flash Sector Lock & Timeout during Program

3. J-Flash RAMCode Timeout during Blank Check

Hi @sochoi 

S32K3 supports only functional flash protection via lock registers SPELOCK, SSPELOCK. This is not permanent protection, it’s just to prevent unintended flash modification, software can update the lock registers as needed. There’s no permanent flash protection feature.

Isn’t there some external watchdog or anything like that?

Also check if you have latest version of J-Link firmware.

Regards,

Lukas

Thank you for your reply. However, there is no external watchdog in our setup, and programming works fine on other devices with the same configuration.

I’ve attached the full log from S32DS below for your reference. Currently, the debugger’s reset command does not work on this device, which appears to be due to the RESET pin not functioning at the hardware level. Could this also be related to the issue?
