From the NVIDIA Tegra Linux Driver Package Development Guide in the “Jetson Module EEPROM Layout” section: Is the “User Data Section” (bytes 89-90 and 91-149) of the EEPROM usable by customers? If the “Customer Overwritable Section” Length field (bytes 154-155) is changed to 16 does the Gigabit Et…

I don’t think we need to strictly define whether “it is for NVIDIA use” or for customer use. It is open-source so you could download the cboot source and modify this part… though I know there is no rel-32 cboot src for TX2 now. You could try to use rel-31 cboot src for now.

Hi, Actually I don’t think bootloader is reading this value… What is the purpose to move mac field from 172 to 160? If no to the previous question, on modules that do not have a WiFi/Bluetooth chip are bytes 160-165 and 166-171 usable for customer defined purpose other than the MAC addresses? …

What does “this value” refer to? The purpose is to have 12 more bytes in the continuous space from 178-254. So the “Reserved for future use.” section goes from 166-254 and is available for storage. I’m not sure I understand your response. You say no, but your explanation makes it sound like yes…

What does “this value” refer to? Ans: “Length field”. I don’t think bootloader is reading this value and use it in any function. I’m not sure I understand your response. You say no, but your explanation makes it sound like yes you can → you just get some error messages. Ans: Sorry, I ju…

So “Reserved for future use” technically means it is reserved for NVIDIA use, not customer use?

I’m currently trying to use R32.3.1 (latest at this time). Is there a C-Boot source release for R32.3.1 yet?

Hi JD, I was wondering if you had success using the “extra” (i.e. Reserved for future use.) bytes in either the “User Data” or “Customer Overwritable Section”? I am interested in using a few bytes to communicate information between userspace and the CBoot. So, I would need read/write access in bo…

Unfortunately, no. Our team is still working on the release. I will update this thread if we release it.
