Leo_W Posted June 13, 2023 Share Posted June 13, 2023 Hi，Digilent I have an arty a7 board, ic11 was abnormally hot after power-on, and after testing, it was judged that ic11 was short-circuited, so I replaced ic11, but ic11 has no voltage output, may I ask what happened?

0 Leo_W Posted June 13, 2023 Author Share Posted June 13, 2023 Does this power chip need programming? Before, the power chip of other boards can be used normally after replacement. Link to comment Share on other sites More sharing options...
0 JColvin Posted June 23, 2023 Share Posted June 23, 2023 Hi @Leo_W, This particular PMIC is a one time programmable chip that needs a separate programmer (a Dialog DA9061/2/3 In-Circuit Programmer, 232-18-A Programmer Board) to be able to configure it. If you have this programmer and the Arty A7 set up with the chip soldered in (which sounds like it is the case), I will send you a private message. Thanks, JColvin Link to comment Share on other sites More sharing options...
