Hello,
I have a question about the use of setup_sdcard.sh when producing 1GB
images on the local filesystem and sourcing pre-built bootloader files for
this image.
When used in a fashion such as this:
setup_sdcard.sh --dtb beaglebone --boot_label BEAGLEBONE --rootfs_label
THIS_LABEL --bbb-flasher --img-1gb omap-minimal-armhf.img --spl custom_MLO
--bootloader custom_u-boot-am335x_evm.img
we get an error when dd is called about here:
+ case "${bootloader_location}" in
+ echo 'Using dd to place bootloader on drive'

+ echo -----------------------------

+ '[' '!' x1 = x ']'
+ dd_spl_uboot='count=2 seek=1 '

+ dd_spl_uboot='count=2 seek=1 conv=notrunc '
+ '[' '!' x128k = x ']'
+ dd_spl_uboot='count=2 seek=1 conv=notrunc bs=128k'
+ '[' xenable = xenable ']'
+ spl_uboot_blob=
+ echo 'MLO: dd if= of=omap-minimal-armhf.img count=2 seek=1 conv=notrunc
bs=128k'
MLO: dd if= of=omap-minimal-armhf.img count=2 seek=1 conv=notrunc bs=128k
+ echo -----------------------------
-----------------------------
+ dd if=/tmp/tmp.DLk52EpElz/dl/ of=omap-minimal-armhf.img count=2 seek=1
conv=notrunc bs=128k

0+0 records in
0+0 records out
0 bytes copied, 0.000236716 s, 0.0 kB/s
So in order for this to work as instantiated above and have the variables
populated for dd at this point, I have to make these modifications to the
script:
diff --git a/omap-image-builder/tools/setup_sdcard.sh
b/omap-image-builder/tools/setup_sdcard.sh
index a86e700e..80355850 100755

Should I be using this script differently in order to source external
pre-built bootloader files? Perhaps this is a not-so-common use case?
Thanks,
Art
