Putting data on eMMC flash memory, without linux?

[mike6789]

Hi there,

I have a TE0720 plugged into a TE0701 carrier.

I was able to create the basic Vivado project with the FSBL and "Hello World" applications and flash that to my module's QSPI via USB (J7 connector, very nifty... )

What I am trying to do now is put some data in the eMMC flash memory that I can read from my C application.

Can anyone point me in the right direction of how to approach this?

Thank you,
Mike

Hi,

the eMMC is not formatted by default. The easiest way is to use linux or u-boot to get access to the eMMC on the TE0720.

Hi,
I've found only this one (Arasan SD 2.0 host controller):

• http://www.wiki.xilinx.com/Baremetal+Drivers+and+Libraries
• http://www.wiki.xilinx.com/Zynq+SD+Standalone+driver
• https://forums.xilinx.com/t5/Zynq-All-Programmable-SoC/SD-Card-example-design-using-standalone-SDK-project/td-p/584170

but no xilinx baremetal example provided with sdk.
