P1010RDB LEDs

Good afternoon,

I am new to the P1010 and the RDB. Are there any usable LEDs on the board that can be actuated from early boot, say in the bootrom?

Are you trying to flashing LEDs by yourself from early boot? I have checked the P1010RDBPBUG.pdf Rev.0, and did not find one usable for the purpose, so I am afraid no. Correct me if this is not your meaning.

Hi,

I found this code in u-boot\arch\powerpc\lib\board.c

#if defined(CONFIG_STATUS_LED) && defined(STATUS_LED_BOOT)

status_led_set(STATUS_LED_BOOT, STATUS_LED_BLINKING);

#endif

This seems to do what you want I don't see a flag used so that this will be executed only

for one processor, this code is used for the all processors from the PowerPC family. The

CONFIG_STATUS_LED flag is used to enable the blinking feature in particular.

Maybe this can be a starting point for you,
