Workaround |
Impact |
---|---|---|---|
Clock tree review still in progress for DM to ensure all clocks are present in the device |
|||
ADASVISION-5063 |
Main R5FSS is booting in secure mode which makes disables the cache coherency between the A72 (insecure) and R5F (secure) on the DDR shared memory region |
Cache on the A72 for this shared memory region is disabled |
Reduced performance will be seen when A72 reads or writes from/to the shared region (such as with reading outputs from the graph to store on an SD card) |
ADASVISION-5064 |
OCMC RAM init failure on MCU2-0 |
Init is disabled and memory previously mapped here is instead mapped to DDR |
Reduced performance of memory previously accessed from this region. In SDK this was only used by heterogeneous camera context save/restore |
ADASVISION-5065 |
The MCU2-1 and C7X-2 often fail to boot on a cold boot |
After a power-on boot invoke a warm “reboot” |
Extra linux boot upon power on. |
ADASVISION-5067 |
C7X-2 MMU table gets corrupted during initialization |
Added 10s delay during init of firmware |
Extra delay during boot. |
