TMS570 Debug board
by Burns Fisher (AMSAT) 08 Dec '23

Zach, I happened to notice that Newark still has some of the DEVPACK boards in stock. Now Newark is not the most reliable of sources, but they are cheap. Anyway, to everyone, I ordered two plus a similar one they Newark listed as a replacement. We'll see what happens. Note to Pacsat folks: It appears (and Zach can confirm) that Zach must have just ADDED a connector into a DNP space on the board...this is based on the pictures. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software*

Pictures of my debug probe

The ribbon cable has the same connector on both ends...Zach replaced the connector on the debug board with one like he has on the RT-IHU (or maybe it was even just changing the gender). You can see the number of the big chip on the bottom, but I could not even make out the numbers on the little one with a bright light and mag goggles. 73, Burns Fisher, WB1FJ *AMSAT(R) Engineering -- Flight Software*

TMS570 JTAG interface
by Corey Minyard 07 Dec '23

It looks like the launchpad uses an XDS100v2 chip for going from USB to serial ports and JTAG. TI's web page on it is https://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_xds100.html The USB device ID would be provided by the XDS100, so as long as you have that chip, it should just work. I've used Olimex before for other things, and that adapter is 55 euro. Anyway, we have options. -corey

Original PacSat Frequencies
by Jim McCullers 01 Dec '23

01 Dec '23

The original PacSats used these frequencies; AMSAT-OSCAR-16 Uplinks 145.9 - 145.92 - 145.94 - 145.96 Downlinks 437.025 - 437.05 LUSAT-OSCAR-19 Uplinks 145.84 - 145.86 - 145.88 - 145.9 Downlinks 437.125 - 437.1 There is no mention that the second downlink was used for packet or telemetry. The article does mention OSCAR-19 had a modified CW beacon for telemetry but does not indicate that was the second downlink. OSCR-16 carried an experimental beacon on 2401.2.
