Tool/software:
hi expert,
My project using TDA4 VH + SDK 9.1. Emmc device type is FEMDME032G-A8A58.
I used MMCSD_EMMC_TestApp_freertos demo for emmc read and write test.
Emmc init is success, but When we try to write emmc using MMCSD_write function, the driver reported data transfer timout. The program is stuck in the code below.
When we try to read emmc using MMCSD_read function, the driver query interrupt status using HSMMCSDIntrStatusGet function. The MMCSD0_NORMAL_INTR_STS register return read command has not completed. The program also stuck.
my question:
1、What are the causes of emmc read/write block and how do I solve them？
2、My project does not use freertos but autosar cp os, does emmc drive depend on osal interface? Do we need to adapt autosar cp os to osal interface?
