Hello,
I have a confirmation about boot time of DM6446.
I am using SPI flash boot which is supported in Silicon Rev 2.3.
I noticed that the 1st ROM bootloader booting time is varied by temperature and target board.
I need to confirm it is assumed operation or not.
My question is:
- Is that assumed operation for DM6446?
- If yes, what can you think the reason to occur this phenomenon?
From our exam:
I attach the waveforms during SPI flash booting.
a) Wave1 (29msec)
b) Wave2 (227msec)
c) Wave3 (906msec)
Best regards, RY
