Hi,
We are following the design of the Jetson AGX Orin, and implementing the same AQR113C chip for the ethernet. I know I have to contact Marvell for the firmware image and the update tool, but my question is another one. The NVIDIA datasheet P3737_A05 says that the AQR113C has a FLASH Memory connected to it (W25Q40EWUXIE). Now, is this the one I have to program so the chip boots up with it?
Because in another post:
Blockquote
it says that NVidia uses a SPI socket to program the chip.
Or, how is the external flash memory programmed?
Hi,
If the device cannot be flashed/booted, please refer to the page to get uart log from the device:
Jetson/General debug - eLinux.org
And get logs of host PC and Jetson device for reference. If you are using custom board, you can compare uart log of developer kit and custom board to get more information.
Also please check FAQs:
Jetson AGX Orin FAQ
If possible, we would suggest follow quick start in developer guide to re-flash the system:
Quick Start — NVIDIA Jetson Linux Developer Guide 1 documentation
And see if the issue still persists on a clean-flashed system.
Thanks!
It is not that the device cannot be flashed. Currently, we are still on the design state, and trying to understand how the chip will be programmed. And if it is actually the external memory that is programmed, which then programs the AQR113C.
Any insight on this would be helpful.
please contact with the vendor directly.
What I am asking is not relating to the firmware flash, but rather what is the chip that needs programming. Since the external memory is a component that NVIDIA places on the schematic. I assume either the AQR113C or the external memory needs to be programmed, and I am asking which one? Or if it is actually both.
What got flashed to the ARQ phy chip is the firmware… we are talking about the same thing here.
With your statement now you are saying that the chip is the one that gets programmed, and not the external memory
What “external memory” are you talking about here? Is that thing related to AQR113C or you are talking about something else?
I am just telling that the only thing that needs to get flashed into AQR113C is just the firmware provided by Aquantia. That thing is not related to any “boot” or “flash” to Jetson itself.
In the screenshot we can see that connected to AQR113C is the external memory W25Q40EWUXIE, and I wanted to know if this external memory is actually the one that gets the firmware into the AQR113C on boot, and if not, what is the purpose of this external memory. This is in the P3737_A05 schematic.
Yes, that W25Q40EWUXIE is where the PHY firmware is located. It is where the firmware got flashed.
We don’t provide the tool and method to flash that. That thing has nothing to do with Jetson. It is using the tool from Aquantia to flash.
Okay thank you. That was what I wanted to know
