Part Number: AM2434
Hi Team,
I have custom board of AM2434 and interfacing it with SFDP supported 1GB quad FLASH.
I have successfully implemented "ospi_flash_diag_am2434" and got all the data, then tried with "ospi_flash_dma_am2434" with DMA enabled, PHY disabled and D0-D3 data pin.
First i have implemented 1S-1S-1S protocol successfully as per the following image
then i tried with 1S-1S-2S and 4S-4S-4S but it stuck in infinite loop. Then after that again i tried with 1S-1S-1S , that protocol also no working, getting following error.
[MAIN_Cortex_R5_0_0] [OSPI] DMA low latency example started... ERROR: App_OspiFlashDmaCompareBuffers:434: OSPI read data mismatch at index 1 !!! OSPI Write 32 bytes in 44216 ns OSPI Read 32 bytes in 5805 ns OSPI Read 32 bytes in 0 ns OSPI Read 32 bytes in 0 ns OSPI Read 32 bytes in 0 ns OSPI Read 32 bytes in 0 ns OSPI Read 32 bytes in 0 ns OSPI Read 32 bytes in 0 ns OSPI Read 32 bytes in 0 ns OSPI Read 32 bytes in 0 ns OSPI Read 32 bytes in 0 ns Average time for OSPI Read 32 bytes in 580 ns Some tests have failed !!!
Same thing was happened before, at that time i did restart and process with diagnosed and dma code with that it was working with 1S-1S-1S. But now its not working
