hi, i wan’t change mac address, and modify the i2c by command: i2cset -f -y 2 0x50 0xac 0x3f now the jetson nano can’t boot, how can fix it? thanks

Hi, Sorry that I missed the nvtboot.bin file. Please try this new tarball and reflash your device. “nvtboot.bin” should be copied under "Linux_for_Tegra/bootlader/t210ref/ " “nvtboot_recovery.bin” should be copied under “Linux_for_Tegra/bootloader/” nvtboot.tar.gz (157 KB)

Our engineer is still investigating your issue. I will update once we find something. Also, still some of my own questions: Are you still have other nano board to use now? Are they working(flash) fine? Are you using a macbook as host?

I don’t have other nano boards to use now. I use a native lubuntu 16.04 notebook as a host.

Hi Lonesomesnow, Can you please provide latest uart logs with latest nvtboot.bin/nvtboot_recovery.bin as provided by WayneWWW and board-config changes as: BOARDID=“3448”; FAB=“200”; BOARDSKU=“0000” ; BOARDREV=“C.0”;

And please paste the command you used to flash and output of: “tail jetson-nano-qspi-sd.conf”, output should be: $ tail jetson-nano-qspi-sd.conf OF THIS SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. BOARDID=“3448”; FAB=“200”; BOARDSKU=“0000” ; BOARDREV=“C.0”; EMMC_CFG=flash_l4t…

Hi, Could you try to compress your Linux_for_Tegra as a tarball. Put it to online storage like google drive or something for us to download? We cannot reproduce your issue with our own driver package. Better directly using your setup.

[url] https://drive.google.com/file/d/1FMbDD8C_wiABLc23FIx8qrP_zA9pqeCD/view?usp=sharing[/url] By the way, I borrow a Nano board from other people to test the flash function, and this Nano board can flash without any error by this tarball.

Please try to use these new nvtboot binary and share the boot log with us. Thanks. nvtboot_20190711.tar.gz (160 KB)

Hi jburman,

I recovered EEPROM with original values, and it works fine now.
Thanks for your explanation.
