DRA821U: Secure boot from PCIe + M.2 SSD.

Part Number: DRA821U

Hi,

Is it possible to boot DRA821U directly from PCIe/SSD?

I see that it is possible to select PCIe as a primary boot option.

Thanks - Eamonn

Hi Eamonn,

Unfortunately, we do not have software support for using PCIe as a primary boot option. Supported boot modes in SDK are listed here: https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-j7200/09_02_00_04/exports/docs/psdk_rtos/docs/user_guide/evm_setup_j7200.html

Hi Takuma,

Thanks very much for your quick reply.

To be clear, is this a software issue (no SDK support at the moment), a hardware issue (no support for SSD boot in the EVM), or a silicon issue (no support for SSD boot in the ROM code)? I'm trying to understand exactly where the problem is, and if it could be solved in a custom board. SSD boot would be a nice option.

Best regards

Hi Eamonn,

Currently, this is a software issue. Hardware-wise, ROM has support for PCIe, but we do not have support for PCIe in secondary program loader (SPL), and U-Boot.

Ok, so this could be solved in the future with an upgrade to the SPL/U-Boot.

I guess in the meantime, we could put a QSPI on board, boot from that, and then switch over to SSD.

Later, if the SPL gets upgraded, we could drop the QSPI off the board and boot directly from PCIe-SSD.

Thanks again, Takuma.

Best regards - Eamonn
