TDA4VM: Access non-SDcard memory in the EVM

Hello experts,

I have been reading this again: https://www.ti.com/lit/ug/spruis4e/spruis4e.pdf

"

2x Octal‐SPI NOR flash, 512 Mb memory (8 bit) + 512 Mb memory (4 bit)
– HyperFlash + HyerRAM, 512 Mb flash memory + 256 Mb RAM
– UFS Flash memory, 32GByte, 2Lane, Gear3
– eMMC Flash memory, 16 GB memory, v5.1 compliant
– MicroSD Card Cage, UHS‐I
– Inter-Integrated Circuit (I2C) EEPROM, 1 Mbit

How do I access emmc to read/write to it?

Searching the SDK docu only gave me this:

The reason I ask is that I would like to boot from it, see how it behaves:

in the EVM setup there is only the mention of beying booted from, but not writing to it:

My end goal is to well, access it somehow, maybe put another Linux in it, test jailhouse or xen ( if I can ever get them to work)
