I2Cset, no boot

Hi jbuttenshaw,

Could you share a summary of what you’ve done to make it able to flash?

It doesn’t boot but it is now flashing.

I started fresh and followed every step mentioned in this thread: after i2cset test, nano can't boot i.e. Applied each of the binaries in sequence and modified the files as mentioned. The only difference being that I’ve only ever used the image created by SDK manager (Jetpack 4.3).

The changes boiled down to:

tail jetson-nano-emmc.conf 
# OF THIS SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

[b]BOARDID="3448";
FAB="400";
BOARDSKU="0000" ;
BOARDREV="C.0";[/b]
EMMC_CFG=flash_l4t_t210_spi_sd_p3448.xml;
BLBlockSize=1048576;
source "${LDK_DIR}/p3448-0000.conf.common";
T21BINARGS="--bins \"EBT cboot.bin; "

Using the “nvtboot_20190711.tar.gz” binaries: https://forums.developer.nvidia.com/uploads/short-url/1q7xzrC3JqGGq3jHiFJL9stuLtq.gz

DFLT_KERNEL_IMAGE="bootloader/${target_board}/p3450-porg/u-boot.bin";

VERFILENAME="qspi_bootblob_ver.txt";

Let me know if you have anything for me to try to make it boot.

Thanks for your help

Will it be able to flash if you don’t apply nvtboot_20190711.tar.gz but only the rest of patch?

I just want to check that because the nvtboot binary was shared for earlier release like rel-32.1 but not rel-32.3. So it is possible to have compatibility issue.

And more precisely, I think the only solution that resolved the issue on rel-32.1 is below patch.

This one should be compatible to rel-32.3.1 so please try this and this one only.

Hi,

We just had a conclusion with another forum user with below post.

Please try this method and see if it can work with you. Actually, we are just doing the same thing. The only difference is not using rel-32.1 nvtboot on rel-32.3.1.
