Earlier versions of Jetson Nano Developer Kits (A02)

[konkhra]

I got my hands on an early version of Jetson Nano developer kit [ A02 } and I am curious if these devices are installed by the SDK Manager on a single partition or multiple partitions like B0x dev kits.

After installing it through SDK manager I’ve noticed some differences compared with later dev kits. A02 has only one partition and at the bootup process I do not see any nvidia logo simillar to B01 4GB Dev Kit that I have.

I am trying to figure out if the installation was successful or not…or maybe it is a hardware issue with this particular device that I have.

I have installed both JetPack 3.6.2 and 3.5.1. Both of them partitioned the microSD card with a single partition.

zram3       252:3    0 246,5M  0 disk [SWAP]

Am I doing something wrong in the installation process?

hello konkhra,

you may check and list the partition label in details,
for example, $ ls -al /dev/disk/by-partlabel

[konkhra]

$ ls -al /dev/disk/by-partlabel

outputs APP

No other partitons. Am I doing something wrong during the installation?

hello konkhra,

please see-also flash configure file, such as… cfg/flash_l4t_t210_spi_sd_p3448.xml
there’re device type=“spi” for flashing bootloader binaries, and it’s only APP partition flashed to SD card.
