I'm working on the DEVKIT MPC5748G rev D under the S32 IDE, using SDK 2.0.
my current SDK:
S32 Design Studio MPC574xx and S32R SDK RTM 2.0.0 188.8.131.52812191911 com.nxp.s32ds.cross.sdk.S32PA_2.0.0.brc.feature.group NXP
the uSDHC module has initiate cycle long as 5 seconds time, which is very long time for our product.
I found that the define of this 5 seconds uSDHC_TC_TIMEOUT_MS in file usdhc_impl.c responsible for it, changing this define to 1 second results sometime to its task to stuck. in all my tries only value with this define set to 5 seconds results OK.
my questions are:
1. is it a known issue ? do you have any fix for that?
2. why it behaves as a delay and not as a timeout, most of times it works with 1 second (even less). why it not break out and save time in initiate uSDHC module ? (it uses its 5 seconds all the time)
Thanks in advance
