I would like to use the TCMRETRY function of your company's ARMV7 chip, but there is little and unclear description of this function in the documentation, so I would like to seek assistance.May I ask how to use this feature and how to implement it specifically?
Hi Delia,
In my system , TCM ECC has been used.
"The typical use of the *TCMRETRY signal is that a read transaction is retried when an TCM ECC error is detected and the error is corrected. Retrying the read transaction can get the correct read value later."
---------------In my system ,when I find ECC error, I will set TCMRETRY to High. but AHBS bus interface stll return error rdata,
Can you provide a simulation waveform test case for the use of TCMRETRY?When should I raise the TCMRETRY signal and return the correct RData data when I discover an ECC error?How to handle when the core receives a high TCMRETRY signal?
Best friends,
