我遇到一个一直进入不了uboot的问题，狂按回车就是进入不了uboot ############################################ I have a problem that I can’t get into uboot. Pressing Enter can’t get into uboot I sudo./flash.sh jetson-nano-qspi-sd mmcblk0p1 when brushing the machine /home/zzy/Desktop/Linux_for_Tegra1/rootfs/boot/extlinux/extl…

Logs in the other URL only occur after Linux loads, so there isn’t much one can examine. We know it fails to find everything needed in boot, but I don’t have any means to narrow it down. You really need that serial console. It might be possible to debug the configuration with a dev kit carrier board…

I want to mention that it is now CBoot, emulating UBoot, but the functionality should be the same (or a compatible subset). The only way to reach that is with serial console. Your video uses an odd CODEC so I can’t see it, but you’d want to use any key other than the return/enter key. What happens i…

这不是编码器的问题，可能是我usb扩展的问题，但是我上电的时候快速按回车键就是进入不到u-boot，这是新刷的机，甚至usb配置都进入不了，不能进入u-boot会导致我后面很多工作做不了希望前辈看看有没有类似的人出现这样错误帖子，我刷机的时候说没有/home/zzy/Desktop/Linux_for_Tegra1/rootfs/boot/extlinux/extlinux.conf is not found, exiting，这是源码问题，还是什么 [image-20230706091109129]

希望前辈看看有没有类似的人出现这样错误帖子，我刷机的时候说没有/home/zzy/Desktop/Linux_for_Tegra1/rootfs/boot/extlinux/extlinux.conf is not found, exiting ，这是源码问题，还是什么這代表你當初準備BSP的步驟有漏… 比方說apply_binaries.sh沒有跑… https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3273/index.html#page/Tegra%20Linux%20Driver%20Package%20Deve…

Some additional information, not an answer: During normal flash a purely Ubuntu “sample root filesystem” is a starting point for the image to be flashed. The “apply_binaries.sh” script (run with sudo) is what adds the NVIDIA drivers (this is done only once). Part of that content includes the extlinu…

前辈我现在刷机卡在这一步一直不进行下去了，我也不清楚什么原因，我还参考官方手册专门写了一个编译的脚本，我刷了两次了还是卡在同一个地方，我又不敢取消了，这个刷机刷一天明显感觉不太正常 [image-20230707182830248] byte copied, 0.00016538 s, 6.0 kB/s assign_string: crc-flash.xml.bin PTHD 65528 4 echo PTHD | dd of=crc-flash.xml.bin bs=1 seek=65528 count=4 conv=notrunc 4+0 records in 4+0 recor…

I consulted the official manual, but it’s stuck in the cboot. I don’t know why

I saw “APX” in the lsusb listing. This means you are probably using a VM. I expect VMs to fail because unless USB is set up correctly, the USB will fail to reconnect after a disconnect (which happens during normal flash).

I will try again today, is it possible that I only compiled the kernel but I did not compile the u-boot

That I don’t know how to answer. I will say though that any USB issue means you won’t get a chance to find out if you compiled only part. Also, it could very easily be all of the content is good, but the network setup for PXE is wrong. Anything which can’t find the content will look about the same. …
