Make sure your ROM base does not include any file-header
|
|
information that is prepended to the kernel.
|
|
|
|
For example, the bootable U-Boot format (created with
|
|
mkimage) has a 64 byte header (0x40). So while the image
|
|
you write to flash might start at say 0x20080000, you have
|
|
to add 0x40 to get the kernel's ROM base as it will come
|
|
after the header.

Reads on the Blackfin are speculative. In Blackfin terms, this means
|
|
they can be interrupted at any time (even after they have been issued
|
|
on to the external bus), and re-issued after the interrupt occurs.
|
|
For memory - this is not a big deal, since memory does not change if
|
|
it sees a read.
|
|
|
|
If a FIFO is sitting on the end of the read, it will see two reads,
|
|
when the core only sees one since the FIFO receives both the read
|
|
which is cancelled (and not delivered to the core) and the one which
|
|
is re-issued (which is delivered to the core).
|
|
|
|
To solve this, interrupts are turned off before reads occur to
|
|
I/O space. This option controls which the overhead/latency of
|
|
controlling interrupts during this time
|
|
"n" turns interrupts off every read
|
|
(higher overhead, but lower interrupt latency)
|
|
"y" turns interrupts off every loop
|
|
(low overhead, but longer interrupt latency)
|
|
|
|
default behavior is to leave this set to on (type "Y"). If you are experiencing
|
|
interrupt latency issues, it is safe and OK to turn this off.

Use the processor's MPU to protect applications from accessing

memory they do not own. This comes at a performance penalty

Sleep "Deeper" Mode (High Power Savings) - This mode reduces dynamic

|
power dissipation by disabling the clock to the processor core (CCLK).
|
|
Furthermore, Standby sets the internal power supply voltage (VDDINT)
|
|
to 0.85 V to provide the greatest power savings, while preserving the
|
|
processor state.
|
|
The PLL and system clock (SCLK) continue to operate at a very low
|
|
frequency of about 3.3 MHz. To preserve data integrity in the SDRAM,
|
|
the SDRAM is put into Self Refresh Mode. Typically an external event
|
|
such as GPIO interrupt or RTC activity wakes up the processor.
|
|
Various Peripherals such as UART, SPORT, PPI may not function as
|
|
normal during Sleep Deeper, due to the reduced SCLK frequency.
|
|
When in the sleep mode, system DMA access to L1 memory is not supported.

If unsure, select "Sleep Deeper".
