S32G Boot Interface Support Query - USB OTG and PCIe Boot

dylee — Tue, 21 Jan 2025 04:09:49 GMT

Dear NXP Community,

I recently purchased an S32G RDB3 evaluation board (currently in transit) and have some questions regarding the boot interface support.

Current Understanding:

I am aware that S32G supports booting from:
1.Quad SPI
2. µSDHC Interface
Specific Question: Does the S32G support Linux boot capability through:

1.USB OTG interface
2.PCIe interface
If these interfaces are supported for booting, could you please provide any relevant documentation or application notes?

Thank you in advance for your assistance.

Hello, @dylee

Thanks for your interest on S32G3RDB

1. For booting the board, as described RDB3 USER Guide, the following 4 methods are supported, including SD/eMMC/QSPI/Serial.

2. If specially booting Linux(from Uboot), then from my experience, it may be supported from USB flash driver and/or SSD(with PCIe or M.2 interface). But sorry that there seems no related documents which targeted for these settings.

Apologize for your inconvenience.
