+.TH SIGROK\-FWEXTRACT\-PX\-LOGIC 1 "Feb 25 2026"
+.SH "NAME"
+sigrok\-fwextract\-px\-logic \- Extract PX Logic firmware
+.SH "SYNOPSIS"
+.B sigrok\-fwextract\-px\-logic
+.SH "DESCRIPTION"
+This tool downloads firmware and FPGA bitstreams from the vendor
+software GitHub repository for the PX Logic USB logic analyzer.
+.PP
+In order to extract the firmware/bitstreams, run the following command:
+.PP
+.B "  $ sigrok-fwextract-px-logic"
+.br
+.RB "  Downloading px-logic-mcu.fw..."
+.br
+.RB "  Downloading px-logic-fpga-stage1.fw..."
+.br
+.RB "  Downloading px-logic-fpga-stage2.fw..."
+.PP
+Copy the resulting files over to the location where libsigrok expects
+to find its firmware files. By default this is
+.BR /usr/local/share/sigrok-firmware .
+.SH OPTIONS
+None.
+.SH "EXIT STATUS"
+Exits with 0 on success, 1 on most failures.
