While the AM62A and AM62D are largely similar, the AM62D is > +specifically targeted for general-purpose DSP applications, whereas the > +AM62A focuses on edge AI workloads. A key distinction is that the AM62D > +does not include multimedia components such as the video encoder/decoder, > +MJPEG encoder, Vision Processing Accelerator (VPAC) for image signal > +processing, or the display subsystem. Additionally, the AM62D has a > +different pin configuration compared to the AM62A, which impacts > +embedded software development. > + > +More details can be found in the Technical Reference Manual: > +https://www.ti.com/lit/pdf/sprujd4 If you have to make another spin of this, one small nitpick is to have this link be consistent with the 'Platform information' section below. > + > +Platform information: > + > +* https://www.ti.com/tool/AUDIO-AM62D-EVM > + ~Bryan
