I've already posted about the PTM problem of i.MX 6 Solox SDB.

 

Out team confirmed that PTM works on i.MX 6QuadPlus SABRE Development Board with emulated JTAG_CLK with same methodology.

 

By the way, we could get a Cortex-A9 PTM Trace too. Connecting J-Link JTAG Emulator to the board, we could get a normal trace from ETB. It seems that connection to JTAG port, and some stages that J-Link Commander do are important for getting PTM Trace.

 

And I think it's kind of hidden errata in this board. Because, its behavior is similar to PTM errata in i.MX 6 QuadPlus, but can be cleared with different method; JTAG Connection + Some Communication with J-Link Commander.

 

But we need to get PTM Trace without connection with J-Link JTAG Emulator. So I want to know the exact condition that makes PTM work on i.MX 6 Solox SDB.

 

Thank you
