I added the MT25QL01GBBB, thank you, but I wonder if it actually works properly since I saw in the datasheet that it uses two 512MBit dies in the package.
But now I wonder what Flash exactly is Riverdi using on their EVE4 modules.
My RVT70HSBNWC00-B is populated with a chip from Micron, the markings are "MT" "IGA17", "RW213" and "FBNP".
My RVT50HSBNWC00-B is populated with a chip from Micron, the markings are "MT" "IIA17", "RW213" and "JBRQ".
My RVT101HSBNWC00-B is populated with a chip from Micron, the markings are "MT" "0DA17", "RW256" and "J2F1".
All do have BGA cases.
A quick search for Micron 512MBit flash chips did not tell me what devices exactly these are.
