AM2432: DRR4 or LPDDR4 Timing Parameters configuration tool

Part number:AM2432

AM2432 supports DDR4 or LPDDR4 ,PCB layout will affet DDRtiming parameters,for example tRTW、tWR、tRC .ect.Causing a decrease in DDR rate and even failure to operate DDR，therefore, we need to configure the timing parameters of DDR based on the actual layout of the PCB. Therefore, do you have a dedicated configuration tool for AM2432?

Yes, either https://dev.ti.com/sysconfig/?product=Processor_DDR_Config&device=AM243x_ALV_beta

or https://dev.ti.com/sysconfig/?product=Processor_DDR_Config&device=AM243x_ALX_beta can be used to configure AM24x devices, depending on package type (ALV or ALX)

Hi James:

Thanks for your reply,I have another question to consult with you，the tREFI（average refresh interval all banks）of ddrx or lpddrx will vary in response to its junction temperature changes,for example IS43/46LQ32256B(ISSI) tREFI=3.904us when Tcase≤85℃，tREFI=1.952us when 85℃＜Tcase≤105℃，tREFI=0.976us when 105℃＜Tcase≤125℃，So, I would like to ask if the tREFI of DDR will change the refresh rate due to temperature changes. Will the tREFI of AM2432 DDR controller be synchronized and adaptive?
