Other Parts Discussed in Thread: AM4376
Tool/software: TI C/C++ Compiler
Hi,
My project have CPU am4376 to bootload the application from QSPI.
I used C:\ti\pdk_am437x_1_0_16\packages\ti\starterware\bootloader\src\sbl_main.c to implement to load application to DDR from QSPI and run it.but I found that clock frequency of QSPI of reading is more than 80 ns, It's so slow that the app takes more than 40 seconds to start.
And I tested that the clock frequency of QSPI of writing program(C:\ti\pdk_am437x_1_0_16\packages\ti\starterware\examples\qspi\flash_writer\flash_writer_app_main.c) is more than 20ns. it take more than 10 seconds to write the same amount of data.
So, I hope to improve the the clock frequency of QSPI of reading by the bootloader.
but I checked the codes and found that there seems to be no difference between the two program about the setting of QSPI peripherals.
Is there any other setting to slow the the clock frequency of QSPI?
