Hello All,
I tried to update imx219 Driver module to L4T R32.2 in my customize Evaluation Board,But Boot now fails with this error:
iso bandwidth %uKB is not available, client
and reboot it later any secend…
it Works OK with the older JetPack 3 releases!!
my DTS module file is:

i find this message in pre_t19x_iso_plat_register function:
kernel/nvidia/drivers/platform/tegra/mc/isomgr-pre_t19x.c
how can i disable this error??
