What is the most direct way to program an eMMC chip on the HPS controller?

I am working on a project, based on a Cyclone V SoC. The HW is equipped with a QSPI FLASH and a eMMC chip, both connected to the HPS pins. We want the system to configure/boot from the eMMC chip. I...

Thanks for your reply,

I have looked at that thread before. I see many users with same issue, but I see no elegant solution.

Usually, when using an eMMC chip, it involves a file-system, which means that a complete SD-card image must be transferred. This is often a few GB, which makes Jtag impractical.

I have only tried the method with U-boot and the debugger.

Our application is a bear-metal application, although we are using FreeRTOS for the Ethernet stack. Therefore I find the Linux method very indirect.

Shortly after posting this question, I found a combination of these methods:

As I understand this, U-boot has a tftp-client and is capable of writing to the eMMC chip.

For me as Engineer, many things are possible, but I have to find a solution, which can be used in the production. Ideally, it is a script/program, which handle all the complicated stuff.
