I did try SDK Manager today using Jetpack 4.2.1 but got the same result. Unfortunately I only have a 5V serial to USB adapter and that gave me only garbled text on the UART. I have ordered a 3.3V adapter but that might take a few weeks.
It still seems only the original SD-Card image is working for me. That is working fine, but it would be nice to be able to update the software.
After some testing, I think the issue is still from the power supply.
test bench:
Jetson nano dev kit
Sandisk 16GB Ultra UHS-1 SD card
load: jetson-nano-sd-r32.2-2019-07-16.img
5V 4A adjustable power supply
issue:
in auto boot mode, plug in the power, the device may either 1) fail to start immediately; or 2) start to boot but fail to boot into Linux after few seconds; or 3) boot successfully.
debug:
- the UART debug gave no dedicated core or software issue. the device may fail any time from the boot 0s - 10s.
- set power supply at 4.9V, the device fail to start every time.
- set power supply at sharp 5.0V, the device may boot or fail, roughly 50% chance.
- if the device fails to start (at 5.0V), unplug the power cable and re-plugin may increase the successful rate.
- set power supply at 5.3V, the device start normally almost every time.
- once it boots successfully, slowly reduce the voltage back to 5V (from 5.3V), the device still is very stable. you can pass any power-hungery testing.
thoughts:
the ATX 5V standard has ±5% (±0.25V) tolerance, which means +4.75 V to +5.25. However, jetson nano board cannot start any point below 5V. It is unknown the issue from the carrier board or the core board itself. Even for right 5.0V it may fail to start randomly. the only effective way to solve the problem is rise the voltage of the power supply to maximum of ATX standard (5.25V). You cannot rise it too high: 1) it may damage your USB or other devices using 5V; 2) the carrier board has protection circuit if you rise the voltage too high (more than 5.6V) the circuit will be cut off.
other thoughts:
- Do not blame the current of the power supply. During boot, jetson nano requires no more than 2A or 10W from the power supply itself.
- most 5V power supply output voltage is around 5.1V. some brands may not that accurate voltage thus it may work or may not work.
possible solution:
- update the datasheet of power supply requirements. using 5.2V 4A power supply.
- update the carrier board design to accept standard ATX 5V.
further consideration:
it is really bad design using microUSB port for power supply. 4A is also huge current requirements for cable and connectors. if possible, update the carrier board using 12V input and change the microUSB port into USB type C port (already designed on PCB), accept PD standard on 12V.
Did you try other power supply? The low threshold of input voltage is 4.5V on nano, please check the voltage on input point on board. Using oscilloscope to capture the voltage drop during power on is necessary to confirm if power supply is capable to power on system. Jetson nano production was validated before ship out, it should be able to power up normally with 4A @ 5V supply if no other devices attached draw much power.
Hi Trumany,
After reviewing the schematics of carrier board design, I am guessing the issue is the protection circuit.
We dont have time to do the solid power drop testing. however we do using the laboratory power supply. I dont think the common user can have better options than us. Also we need to notice that if you are using certain length cable to deliver the power, you cannot require too much on transient response from power supply side.
I am still guessing the issue:
- there is not enough capacitance from input 5V pin. the input power drops at certain level during boot and protection circuit kicks in. terminate the whole power.
- for some reason the protection circuit need some time to be fully recovered. if it kicks in one time, it will keep disconnect the input line more strictly in short period of time.
If it is dev kit, the capacitors and protection circuit should be no problem except something on board broken or external device drawing too much current during power-on. It is really necessary to probe the real voltage on the input point on the board to verify it is 5V indeed to board. To confirm if any voltage drop during power on is also important. A good cable and a stable power supply are necessary for power-on with heavy load.
I finally got my ttyUSB adapter working so here is the output from the boot procedure. The boot is extremely slow and is booting the card image r32.2.1. After printing some errors on screen when loading Kernel Modules, Kernel Variables and udev Kernel Device Manager the system gets a kernel panic.
