Hey, if you're interested in doing signal processing on embedded devices using OpenEmbedded, and maybe shy away from corporate pricing for OE workshops:
@gnuradio #GRCon25 features a workshop "GNU Radio on Embedded SDRs" by Philip Balister @Crofton (of OE fame) and Toby Flynn (of RedWire Technologies).
There's week/1day tickets available & if you're into SDR, #GPU-accelerated DSP, satellite comms, radio astronomy, physics with SDR, DSP architecture, radio metrology, …, it's a really nice conf.
