PRUCAPE: TIDU426 orange and green LED swapped ?

Peter Vittali
Expert 2015 points
Part Number: PRUCAPE

The mentioned document states (table 1) that:

MCASP0_FSX is connected to  PRU0 Orange LED

MCASP0_AXR0 is connected to PRU0 Green Led

Based on my tests, these are swapped, that is MCASP0_FSX => Green and MCASP0_AXR0 => Orange

Thanks

Peter

    1. The PDF document PRU CAPE Hardware TIDU426 from July 2014 has the following (the incorrect mapping for PRU0 Orange and Green LEDs based upon your tests):

    2. The PRUCAPE schematic tidr938 has the following (the correct mapping for PRU0 Orange and Green LEDs based upon your tests):

    3. The PRU Cape Hardware User Guide WikiPage has the following (the correct mapping for PRU0 Orange and Green LEDs based upon your tests):

    The revision history for the WikiPage showed that in September 2015 the mapping for the PRU0 Green and Orange LEDs were corrected.

    I.e. the LED mapping is incorrect in TIDU426, but has been corrected in the WikiPage.
