Dear Sir,

We know Nvidia changed the eMMC vendor for TX1.
If it is Sandisk, it needs to use the L4T version above R28.2. (PCN205040-Jetson_TX1_Multiple_Changes9.pdf)
(This is why we need to upgrade from L4T R24.2.1 to R28.2)

We use this command to read eMMC ID.

cd /sys/block/mmcblk0/device && grep ^ manfid

Toshiba = 0x11
Sandisk = 0x2（expected）

#define CID_MANFID_SANDISK    0x2
#define CID_MANFID_TOSHIBA    0x11
#define CID_MANFID_MICRON    0x13
#define CID_MANFID_SAMSUNG    0x15
#define CID_MANFID_HYNIX    0x90
#define CID_MANFID_NUMONYX_MICRON 0xfe

We got the value 0x45 from our factory.
What is the vendor for the value 0x45?
What is the L4T version for it?

Hi,
Please check

It looks to be a race condition in K4.4.

Hi DaneLLL,

Can I say that the eMMC ID 0x45 is also Sandisk?

Thanks.
