NXP S32G3:Secure boot :Delay before XRDC Init

[kavyapk]

Hello Team,

Board: S32G399RDB3 with Autosar application in M7 core ,and BSP.V.42 used in the A core

Secure boot enabled bootloader with HSE FW HSE_FW_S32G3XX_0_2_51_0.

Observation:Once secure boot config  and further reset is done , NXP Bootloader will be running where we are observing issue RM initialization in sysdal_deinit .

Error :Hardfault

To resolve this we put some dealy before sysdal_deinit and it is working.

Since this delay effects the overall time for application running when secure boot is enabled we need to understand this behavior.

This was running without delay when secure boot is disabled.

Could you please help us to understand the reason behind this.

Thankyou

Hello @kavyapk,

Thanks for reaching out to us. About your problem, can you share the following details:

• Are you powering EFUSE_VDD? if so, how and in which state of the booting process is that supply connected to the SoC?
• Which are the permissions set by XRDC for HSE module?
• Have you checked the status of the HSE with and without the added delay? If so, which are the statuses you are seeing in those cases?
• Given that the HSE_Status() function only prints the status to the serial terminal, can you test without calling that function?
• Have you testes several delay values? if so, which is the smallest delay value that solves the problem?
• Can you share the InitList of the SystemPowerUpConfiguration?

Thanks in advance for the information.
