Other Parts Discussed in Thread: TMS320DM647 Hello, The Documentation is confusing to me so I've got to ask. I want to use the User Defined LEDs on my EVM board which are tied to GPIO2-GPIO5, but I'm not having any luck. I believe I am setting up the…
Hi Dan,
What boot mode is the EVM set to? Please take a look at the "Using the TMS320DM647/DM648 Bootloader" appnote to understand how the bootloader programs the PLL for each boot mode. Also, are you loading a GEL file in CCS? If so, there is a function…
Other Parts Discussed in Thread: TMS320DM647 hi,
we are testing our dm648 board, but can not power on vedio port 3 by setting LPSC register. we debuged the function in pal_sys.c of psp driver, and check the procedure on page 59 of sprueu6b(TMS320DM647…
Hi Brad,
Looks like we found the cause of problem.
It seems to be related to a DM647/8 silicon issue. Advisory 1.1.5, SDAM/IDMA: When DSP Level 2 memory is configured as non-cache (RAM) unexpected blocking and potential deadlock condition may occur…
May I recommend you review the follow document?:
