Barry Songd86bfb12010-01-07 04:11:17 +0000409 Make sure your ROM base does not include any file-header
410 information that is prepended to the kernel.
411
412 For example, the bootable U-Boot format (created with
413 mkimage) has a 64 byte header (0x40). So while the image
414 you write to flash might start at say 0x20080000, you have
415 to add 0x40 to get the kernel's ROM base as it will come
416 after the header.

676 registers as a clock source. Doing so means you will be unable to
677 safely write to the 'cycles' register during runtime. You will
678 still be able to read it (such as for performance monitoring), but
679 writing the registers will most likely crash the kernel.

943 Reads on the Blackfin are speculative. In Blackfin terms, this means
944 they can be interrupted at any time (even after they have been issued
945 on to the external bus), and re-issued after the interrupt occurs.
946 For memory - this is not a big deal, since memory does not change if
947 it sees a read.
948
949 If a FIFO is sitting on the end of the read, it will see two reads,
950 when the core only sees one since the FIFO receives both the read
951 which is cancelled (and not delivered to the core) and the one which
952 is re-issued (which is delivered to the core).
953
954 To solve this, interrupts are turned off before reads occur to
955 I/O space. This option controls which the overhead/latency of
956 controlling interrupts during this time
957 "n" turns interrupts off every read
958 (higher overhead, but lower interrupt latency)
959 "y" turns interrupts off every loop
960 (low overhead, but longer interrupt latency)
961
962 default behavior is to leave this set to on (type "Y"). If you are experiencing
963 interrupt latency issues, it is safe and OK to turn this off.

1262 power dissipation by disabling the clock to the processor core (CCLK).
1263 Furthermore, Standby sets the internal power supply voltage (VDDINT)
1264 to 0.85 V to provide the greatest power savings, while preserving the
1265 processor state.
1266 The PLL and system clock (SCLK) continue to operate at a very low
1267 frequency of about 3.3 MHz. To preserve data integrity in the SDRAM,
1268 the SDRAM is put into Self Refresh Mode. Typically an external event
1269 such as GPIO interrupt or RTC activity wakes up the processor.
1270 Various Peripherals such as UART, SPORT, PPI may not function as
1271 normal during Sleep Deeper, due to the reduced SCLK frequency.
