Is SAME70 lacking UART HW-FIFO?
Hi Steve, thank you for your help. It answers my questions well beyond satisfaction. I now really want XDMAC based drivers :-)   I'll close this thread as the question...

Is SAME70 lacking UART HW-FIFO?
Hi Steve, thanks for your reply.   Our primary concern is back-to-back byte transfer within 2.5 TX-bits (=650nS at UART bitrate of 6Mbps).   We need to avoid...

SW equivalent to ERASE pin
The device is a SAME70J21. I assumed the GPNVM SW ability would be the same for all ARM based devices.   Thanks for the reply, this answers my question.   Will implement...

SW equivalent to ERASE pin
Thanks David, I assume you mean the primary bootloader (I'll refer to it as PBL from now on) i.e. at adress 0x0 something like below snippet:    #define ...

SAME70N21: PD7 & 7 pinned as driving high level output
I finally got to it to start-up another board. Needed some patching as some HW design errors needed correcting (which is probably where it went wrong on the previous board)....

SAME70N21: PD7 & 7 pinned as driving high level output
To be more specific about non-SW/FW intervention:   Can we have inadvertently triggered the Embedded Trace Macro-cell (ETM)? Looking at "Figure 16-1. Debug and Test...

SAME70N21: PD7 & 7 pinned as driving high level output
Hi Josh and thanks! Agreed, that sounds like a good practice.   Assuming the case, how is this exactly done? ASF and Atmel are new to me and don't know how to re-set/re-...

SAME70N21: PD7 & 7 pinned as driving high level output
Hi Josh, great to know!   As much as I would like not to, yes - it is possible. We've been very careful and HW-error is usually the last thing to look at when everything else...
