Unboxing the Qualcomm RB5 Robotics Kit

Today I'll be showing some of my very first interactions with a Qualcomm RB5 Robotics Kit. In their words:

The Qualcomm Robotics RB5 development kit combines the promise of 5G with the computing power for AI, deep learning, computer vision, 7-camera concurrency, rich multimedia and security

Inside the box, we get three parts:

  1. The board itself,
  2. A USB-C cable,
  3. A power brick.

Inside the box, there's the RB5 main board, a USB-C cable, and a power brick

RB5 main board, USB-C cable, and a power brick

The bringup guide tells us we'll need a Linux workstation, and a few utilities from the Android SDK: adb & fastboot. In short, it looks like a familiar programming model:

  1. Build device images on your local machine;
  2. Deploy and run those images on the device.

I'm on a Mac right now, so I won't have access to the full toolset needed to prepare the images. However, I've got a working adb and fastboot, so can easily interact with the device. This will likely continue to be my workflow, even after I get a Linux build host going in EC2.

Let's get the kit running. I connect the power brick, and then I connect the USB-C cable into my MacBook. After a bit, a green LED indicator lights up on the device:

At this point, I'm able to see the device via adb:

$ adb devicesList of devices attachedZTR10S1600CS    device

I can even login and probe for some details:

$ adb shellsh-4.4#

The device is running Ubuntu 18.04.05:

sh-4.4# lsb_release -a No LSB modules are available.Distributor ID: UbuntuDescription:    Ubuntu 18.04.5 LTSRelease:    18.04Codename:   bionic

The processor has 8 cores:

sh-4.4# nproc 8

It's an AArch64:

sh-4.4# cat /proc/cpuinfo | grep ^Processor Processor   : AArch64 Processor rev 14 (aarch64)
sh-4.4# uname -a Linux qrb5165-rb5 4.19.125 #1 SMP PREEMPT Sat Mar 20 11:48:10 CST 2021 aarch64 aarch64 aarch64 GNU/Linux

The board has 7650MB of memory:

sh-4.4# free -m              total        used        free      shared  buff/cache   availableMem:           7650        1112        6058          12         478        6848Swap:          3825           0        3825

There are a few USB devices on the board, an AX88179 ethernet controller, and a couple of USB hubs:

sh-4.4# lsusb Bus 002 Device 003: ID 0b95:1790 ASIX Electronics Corp. AX88179 Gigabit EthernetBus 002 Device 002: ID 05e3:0625 Genesys Logic, Inc.

Not much on the PCI bus:

sh-4.4# lspci 00:00.0 PCI bridge: Qualcomm Device 010b (rev ff)01:00.0 Unassigned class [ff00]: Qualcomm Device 1101 (rev ff)

Lots and lots of partitions:

sh-4.4# mount /dev/sda7 on / type ext4 (rw,relatime)devtmpfs on /dev type devtmpfs (rw,relatime,size=2671320k,nr_inodes=667830,mode=755)sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime)proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)securityfs on /sys/kernel/security type securityfs (rw,nosuid,nodev,noexec,relatime)tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000)tmpfs on /run type tmpfs (rw,nosuid,nodev,mode=755)tmpfs on /run/lock type tmpfs (rw,nosuid,nodev,noexec,relatime,size=5120k)tmpfs on /sys/fs/cgroup type tmpfs (ro,nosuid,nodev,noexec,mode=755)cgroup on /sys/fs/cgroup/unified type cgroup2 (rw,nosuid,nodev,noexec,relatime,nsdelegate)cgroup on /sys/fs/cgroup/systemd type cgroup (rw,nosuid,nodev,noexec,relatime,xattr,name=systemd)cgroup on /sys/fs/cgroup/memory type cgroup (rw,nosuid,nodev,noexec,relatime,memory)cgroup on /sys/fs/cgroup/pids type cgroup (rw,nosuid,nodev,noexec,relatime,pids)cgroup on /sys/fs/cgroup/net_cls,net_prio type cgroup (rw,nosuid,nodev,noexec,relatime,net_cls,net_prio)cgroup on /sys/fs/cgroup/freezer type cgroup (rw,nosuid,nodev,noexec,relatime,freezer)cgroup on /sys/fs/cgroup/cpu,cpuacct type cgroup (rw,nosuid,nodev,noexec,relatime,cpu,cpuacct)cgroup on /sys/fs/cgroup/devices type cgroup (rw,nosuid,nodev,noexec,relatime,devices)cgroup on /sys/fs/cgroup/perf_event type cgroup (rw,nosuid,nodev,noexec,relatime,perf_event)cgroup on /sys/fs/cgroup/schedtune type cgroup (rw,nosuid,nodev,noexec,relatime,schedtune)cgroup on /sys/fs/cgroup/blkio type cgroup (rw,nosuid,nodev,noexec,relatime,blkio)cgroup on /sys/fs/cgroup/cpuset type cgroup (rw,nosuid,nodev,noexec,relatime,cpuset)cgroup on /sys/fs/cgroup/debug type cgroup (rw,nosuid,nodev,noexec,relatime,debug)mqueue on /dev/mqueue type mqueue (rw,relatime)debugfs on /sys/kernel/debug type debugfs (rw,relatime)tmpfs on /var/volatile type tmpfs (rw,relatime)configfs on /sys/kernel/config type configfs (rw,relatime)fusectl on /sys/fs/fuse/connections type fusectl (rw,relatime)/dev/sde9 on /dsp type ext4 (ro,nosuid,nodev,noexec,noatime,discard,noauto_da_alloc,data=ordered)/dev/sde4 on /firmware type vfat (ro,nodev,noexec,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)/dev/sde5 on /bt_firmware type vfat (ro,nodev,noexec,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)adb on /dev/usb-ffs/adb type functionfs (rw,relatime)

Looks like a 128GB storage chip, split apart into different partitions:

sh-4.4# df -hFilesystem      Size  Used Avail Use% Mounted on/dev/root        99G  6.0G   93G   7% /devtmpfs        2.6G     0  2.6G   0% /devtmpfs           3.8G     0  3.8G   0% /dev/shmtmpfs           3.8G   12M  3.8G   1% /runtmpfs           5.0M  4.0K  5.0M   1% /run/locktmpfs           3.8G     0  3.8G   0% /sys/fs/cgrouptmpfs           3.8G     0  3.8G   0% /var/volatile/dev/sde9        59M   24M   34M  42% /dsp/dev/sde4       395M   61M  335M  16% /firmware/dev/sde5        64M  368K   64M   1% /bt_firmware

We've found some of the components in the hardware spec sheet so far, but just a few. Of particular interest, I'd like to locate some of the coprocessors (the "heterogeneous computing" bit):

  1. Qualcomm Adreno 650 GPU
  2. Qualcomm Hexagon DSP
  3. Qualcomm Spectra 480 image processing
  4. Adreno 665 VPU video encode/decode
  5. Qualcomm Secure Processing Unit SPU240
  6. Qualcomm Neural Processing unit NPU230

In an upcoming article, we'll start trying to exercise some of these components!
