how i can flash and update only BCT table ?

Hi nvteam,

i had made two cfg files using pinmux spreadsheet
two files are
tegra186-mb1-bct-pad-quill-p3310-1000-c03.cfg and tegra186-mb1-bct-pinmux-quill-p3310-1000-c03.cfg
and i got these files through the procedure below link
https://devtalk.nvidia.com/default/topic/1031959/question-about-changing-tx2-pinmux-/#5261800

and then until recent, i used flash.sh command to apply the files above
just like this command form

$ ./flash.sh jetson-tx2 mmcblk0p1

but the command above was needed so much time and
the command below seems not perfectly applied the cfg files above to my tx2 board

$ ./flash.sh -r -k kernel jetson-tx2 mmcblk0p1

how i can update the cfg files to the tx2 board which are made using pinmux spreadsheet ??

hello parkjeho,

we will investigate this internally, will get back to you once we come out conclusion.
thanks

Hi JerryChang

thanks, i will wait your reply~

Hi,

Is there any update about this?

hi all,

BCT contains next level bootloader’s signature and other loader info. these info need to be retrieved from board.
hence, we currently do NOT have the support to flash only BCT partition yet.
please follow the procedure to flash the device entirely.
thanks

I have a custom L4T(28.1) folder with modified BCT. If i flash a backup image to TX2 using this folder, will BCT be applied to device?
