TMDS273EVM, TMDS273GPEVM, TPR12REVM AM273x EVM LEDs

Figure 2-4 AM273x EVM LEDs
Table 2-5 LED Information
Ref Color Usage Comments Image
D12 Green 12V supply indication This LED indicates the presence of 12V supply input. TMDS273EVM, TMDS273GPEVM, TPR12REVM
D16 Green 5V PMIC Supply This LED indicates the presence of 5V supply output from PMIC. TMDS273EVM, TMDS273GPEVM, TPR12REVM
D2 Green 5V FE Supply This LED indicates the presence of 5V supply for FE connectors. TMDS273EVM, TMDS273GPEVM, TPR12REVM
D13 Yellow nRESET This LED is used to indicate the state of nRESET pin. If this LED is glowing, then the device is out of reset. TMDS273EVM, TMDS273GPEVM, TPR12REVM
DS2 Red NERR_OUT Glows if there is any HW error in the AM273x device. TMDS273EVM, TMDS273GPEVM, TPR12REVM
D9 Yellow WRMRST Open drain fail safe warm reset signal. TMDS273EVM, TMDS273GPEVM, TPR12REVM
D6 Green GPIO_2 Glows when the GPIO_2 is logic-1. TMDS273EVM, TMDS273GPEVM, TPR12REVM
