CMICX LED Interface has two RAM Banks, as shown below, Bank0(ACCUMULATION RAM)
|
|
for accumulation of status from ports and Bank1(PATTERN RAM) for writing
|
|
LED pattern. Both Bank0 and Bank1 are of 1024x16-bit, each row representing
|
|
one port.

The custom handler in this file should read port status, for each port used,
|
|
from accumulation ram, and form required LED bit pattern in the Bank1 RAM
|
|
(pattern RAM) location corresponding to the port of interest. Note that
|
|
physical port numbers may differ from row number of LED RAM Banks. For
|
|
Trident3, Physical port numbers spread from 1 to 128 in 128x25G configuration
|
|
and corresponding LED rows spread from Row 0 to Row 127.
|
|
|
|
There are five LED interfaces in CMICX based devices. Although single
|
|
interface can be used to output LED pattern for all ports, it is possible
|
|
that more than one interface can be used in the end system, e.g., LEDs for
|
|
some ports are connected to one LED interface-0 (i.e LED_CLK and LED_DATA),
|
|
while the rest of the ports are connected to LED interface-1. Accordingly,
|
|
custom handler MUST fill in start port, end port and width of pattern in the
|
|
soc_led_custom_handler_ctrl_t structure passsed to custom handler. The
|
|
example custom handler provided in this file has reference code for forming
|
|
two different LED patterns. Please refer to these patterns before writing your
|
|
own custom handler code.
|
|
|
|
The soc_led_custom_handler_ctrl_t structure definition is available in
|
|
$SDK/include/shared/cmicfw/cmicx_led_public.h
|
|
|
|
soc_led_custom_handler_ctrl_t structure also carries a point to array
|
|
port_speed[] of size equal to maximum ports in the system, e.g 128 in Trident3.
|
|
This array would have port speed for each port, as per bit mapping defined in
|
|
"soc_led_speed_t" in $SDK/include/shared/cmicfw/cmicx_led_public.h file.
|
|
|
|
Here is an exception, please keep in mind:
|
|
1. For TH3, port status/speed of xe1 (physical port 258) is located in the
|
|
accumulation entry/speed array of physical port 259.
