Hello,
I'm trying to get a bitwise operation working in a bitbake bblcass
function but no luck so far :
my_function() {
SZ="`wc -c < ${1}`"
ALIGN_SZ=$(((${SZ} + 0x1000 - 1) & ~ (0x1000 - 1)))
.......
}
Bitbake complains with :
ERROR: ExpansionError during parsing
/opt/Projects/Yocto/meta-somelayer/recipes-kernel/linux/linux-imx_4.1.15.bb:
Failure expanding variable my_function: NotImplementedError: $((
Any suggestions how to tackle this problem ?
Thank you !
