Hi,
I'm trying to get behind the sequence of Flash programming over JTAG. The ECU is a 5775K.
I'm flashing with Lauterbach the following .mot record:
S2 14 F9C000 47524D5354524D0000801511AA5AA555 62
The Signal Analyzer shows the following TDI/TDO Values:
My question is about the bold parts. What command is 53DD0000? Is it e_lwz?
And the part which confuses me the most is the last TDO. The desired address is selected with the 2.TDI and after that the value which should be written to this address is now in TDO. Can anyone explain this to me? If the Data would be in TDI everything would be clear, but this part I don't get..
Maybe someone can help me :smileyhappy:
Thanks in advance

Hi,
what is your goal? If you want to develop own JTAG programmer, take a look at:
https://www.nxp.com/docs/en/application-note/AN4365.pdf
and
Example JTAG access – Addendum to application notes AN3283 and AN4365
It's written for MPC56xx but most of the information is valid also for MPC57xx family.
Regards,
Lukas
