Other Parts Discussed in Thread: OMAP-L138
One of my customer does not use Linux.
And they do search about OMAP-L138 boot.
They know ARM boots first, and sprab41 describes about ARM boot sequence.
But, They are wondering about DSP core sequence.
When I checked the MDSTAT15 register in OMAP-L138EVM,
DSP core was enabled in some boot-mode, and it was disabled in other mode like below.
(MDSTAT15 indicates the PSC state of DSP core.)
NOR EMIFA boot .. disable
NAND-8 EMIFA boot .. disable
SPI1 Flash boot .. enable
UART2 boot .. disable
EMU Debug boot .. enable
Also when I checked armubl, ARM does disable DSP core.
Could you let me know?
- What does DSP core do after SPI1 Flash boot?
- Does the ARM have to do disable DSP core in some boot-mode? (like armubl)
Best Regards.
