Other Parts Discussed in Thread: TDA4VH, TPS62873
Tool/software:
Hi all,
We encountered DDR Timeout During Frequency Handshake using TDA4VH, start the log as follows. The DDR model is the same as that of J78S4 EVM board, the DDR driver of uboot is the same as that of TDA4VH EVM board, and the hardware Layout has passed 4266MHZ simulation and Micron test, with test report.
Our test is as follows, sleep wake test at room temperature, run 90s, sleep 90s is a cycle, the current DDR handshake failure is repeated once an hour on average.
The following log appears, the recurrence probability is low, but we want to solve this problem.
Thanks
