Tool/software: Linux
Hello Sir,
We have connected eMMC IC (MTFC4GACAJCN-4MIT) on MMC1 Interface of processor AM3359, for booting the processor.
Is this eMMC IC (MTFC4GACAJCN-4MIT) is compatible with processor AM3359?
Kindly confirm it.
Regards,
Vamsi
Please read my last post above. I think it's obvious that while AM335x MMC is not v5.0 compatible, eMMC v5.0 memories ARE BACKWARD COMPATIBLE to older versions of the JEDEC/MMC standard, therefore they CAN BE USED with AM335x devices.
Thanks for the immediate response.
In our custom board we have connected eMMC IC (MTFC4GACAJCN-4MIT) with AM3359 processor to MMC1 as shown in the picture below.
Please confirm our schematic, particularly AM335x_MMC1_RSTN and AM335x_MMC1_DS.
Regards
Vamsi
Why it is showing uuid as dead for eMMC. Here device 0 is SD Card and device 1 is eMMC.
=> mmc part
Partition Map for MMC device 1 -- Partition Type: DOS
Part Start Sector Num Sectors UUID Type
1 2048 32768 7001dead-01 0e Boot
2 34816 7485440 7001dead-02 83
=> mmc dev 0
switch to partitions #0, OK
mmc0 is current device
=> mmc part

Hello Vamsi,
Can you post again the output of mmc part and mmc info for mmc dev 1?
=> mmc dev 1
=> mmc part
=> mmc info
Then, do these steps from this post to change the UUIDs. Reset the board and post these mmc info and part outputs for mmc dev 1 again.
=> reset
=> mmc dev 1
=> mmc part
=> mmc info
Also can you post your board's eMMC pinmux settings in <Processor SDK>/board-support/u-boot-<version>/board/ti/am335x/mux.c and pinmux_emmc_pins and &mmc2 node content in <Processor SDK>/board-support/u-boot-<version>/arch/arm/dts/<your-board's-device-tree>.dts?
This issue was solved here.
Best regards,
Kemal
