Clarification needed with "Keystone 66AK2E02" and "MCSDK"

Hi Ajith PV,

Splitted this query as a new one as appending queries on the same thread will only get less attention.

Also I would like to know, is DDR stress test already included in u-boot? May I know what kind of test (s) I can perform on DDR with the available EVK U-boot source code?

I would suggest you to boot the u-boot on 66AK2E EVM and check using the "help" command or "?" . For example, like below:

The following are the tests you can perform related to DDR

Usage:
ddr test <start_addr in hex> <end_addr in hex> - test DDR from start address to end address
ddr compare <start_addr in hex> <end_addr in hex> <size in hex> - compare DDR data of (size) bytes from start address to end address
ddr ecc_err <addr in hex> <bit_err in hex> - generate bit errors in DDR data at <addr>, the command will read a 32-bit data from <addr>, and write (data ^ bit_err) back to <addr>

From ARM’s point of view, we would like to know the following peripheral supports are already present or not in the Linux Kernel as well as U-boot level for validating purpose? If some peripherals are supporting in the Linux kernel but not in u-boot, then please let me know that too.

For your first question regarding the list of peripheral support on u-boot, I would recommend you to go through the source code of it.

Visiting the ARM bootloader user guide for Keystone-II might also be helpful:

Hi,
You can find maximum driver support which you mentioned in both u-boot and Linux as well.

You can find out that information from the screen shot given by Shankari.

I2C -> i2c command support is available.
SPI -> sf command support is available.
EMIF -> nand command support is available.
UART -> debug log.
PHY -> tftpboot,dhcp commands are available (Ethernet).
GPIO -> I hope, you can access the GPIO inside the u-boot code.
EDMA -> Need to check.
