In LimeSDR XTRX v1.2 BOM_VER = 0 boards and earlier versions, the PERST control was not properly implemented. As a workaround, soldering a 0-ohm resistor at R114 offers a simple solution, though it is not ideal. In this case, the PERST signal directly controls the entire board’s power supply, which is suboptimal and should be avoided. The correct approach is to use the PERST signal to properly control the PCIe core within the FPGA. This issue was resolved in LimeSDR XTRX v1.2 BOM_VER = 1 and l…
