help with removing EEPROM for custom Orin Nano carrier with Scarthgap

[arrow53]

I need to zero out the cvb entry cvb_eeprom_read_size = <0x0>; with file tegra234-mb2-bct-misc-p3767-0000.dts

there are some tips here but I'm struggling to sort it out.

I made a custom layer with meta-eeprom/recipes-bsp/tegra-binaries/tegra-bootfiles_%.bbappend that has

SRC_URI += "file://tegra234-mb2-bct-misc-p3767-0000.dts"

do_install:append() {
  install -d ${D}${datadir}/tegraflash
  install -m 0644 ${UNPACKDIR}/tegra234-mb2-bct-misc-p3767-0000.dts ${D}${datadir}/tegraflash/
}

FILES:${PN} = "${datadir}/tegraflash/tegra234-mb2-bct-misc-p3767-0000.dts"

But, I get this error even though my custom version of the dts file is in my files directory.

ERROR: /yocto/orin-nano-scarthgap-sd/layers/meta-tegra/recipes-bsp/tegra-binaries/tegra-bootfiles_36.3.0.bb: Unable to get checksum for tegra-bootfiles SRC_URI entry tegra234-mb2-bct-misc-p3767-0000.dts: file could not be found

See suggestions in https://docs.yoctoproject.org/dev-manual/layers.html#following-best-practices-when-creating-layers and in https://docs.yoctoproject.org/ref-manual/variables.html#term-FILESEXTRAPATHS

It seems you are missing FILESEXTRAPATHS:prepend as discussed there.

thanks @dwalkes yeah, I had thought SRC_URI would look in files but guess not.

For anyone that comes across this. I ended up doing two recipes:

tegra-binaries_%.bbappend gets the file.

FILESEXTRAPATHS:prepend := "${THISDIR}/files:"

SRC_URI += "file://tegra234-mb2-bct-misc-p3767-0000.dts"

Then I move into place with tegra-bootfiles_%.bbappend

do_install:append() {
  install -m 0644 ${S}/../sources-unpack/tegra234-mb2-bct-misc-p3767-0000.dts ${D}${datadir}/tegraflash/
}

I think I could do a better job with the relative file locations / names, but this does work.
