hi JP 5.1.3 HW orinnx 16GB I did a test that reboot orinnx repeatly very 20 seconds after nv-l4tbootloader-config.service boot up successfully at slot A. But it switched to slot B unexpectly and it reported bootloader of slot A was unbootable. Then powered off orinnx module and powered on orinn…

Hi @sebastien.schertenleib Please make sure the bpmp binary is updated successfully: [ 2.889447] tegra-bpmp bpmp: firmware: d04b2652e7d6608668b8-1f2b0ba9331 orin nano 87065653ea95ae3c75f0-1f2b0ba9331 Orin NX d04b2652e7d6608668b8-1f2b0ba9331 AGx Orin series c1ccf05658dadaae760b-1f2b0ba9331 a844…

No, just one of our comstomize board reported it.

Hi, After contacting our Nvidia representative, we are dispatching a full repro, that is a nano devkit with a SSD and a faulty orin nx using vanilla sample BSP 35.6.2 as provided by Nvidia. The full repro also automate the reboot at the right time and logs events to highlight when the issue occurs…

Hi I have tested the patch file “ overlay_mb1bct_35.x.tbz2 ” and the description of it is “This overlay fixes a boot issue caused by the QSPI read timing not having sufficient margin to cover process, voltage, and temperature variations. “ the rate of the issue decrease too much the content of t…

Hi @smileandcry2023 The overlay fixes the issue: Jetson Orin Nano boot failure with temperature dependency 核心板无法启动 You may try 0x2 to see if stability improves further.

Hi Dane, What about the full repro we have sent to Nvidia Taiwan that include the nano devkit, a problematic orin nx module and detailed instructions to reproduce it? What about the investigation on the PCIe C4 failing to detect NVMe SSD in booting, triggering system hangs in booting as reported b…

Hi, We just received the developer kit. Will set up and try to reproduce the issue. One quick question, can we re-flash it? Or have to use the re-flashed system?

Hi, The devkit is already pre-flashed with a full repro that logs events and highlight if the boot swap has happened. I recommend to use UART for collecting logs for the hang use case. You should have received a pdf file that explain how to check the logs, as well as full instructions if you want …

Hi, Our Nvidia representative informed us that investigations were started on your end. Was the description on how to check the issue in the provided document clear enough or do you need any further explanations? Thanks
