AM2434: How to format the eMMC in AM2434-EVM

Hi Weijian

Have you looked at the Uniflash tool in the SDK for this?

Hi Karan

I used UniFlash_8.6.0 and was able to write "sbl.tiimage" and ".appimage" files to Flash. However, on the AM2434-EVM, it seems that the tool could not write files to the eMMC. Unfortunately, I also did not find a way to format the eMMC memory.

Can you explain the steps to format the eMMC in detail? Thank you very much.

Weijian 

Hi Weijian,

Please use UART Uniflash script from the MCU+ SDK itself to flash the eMMC

You can use the below shown config file with UART Uniflash

~/ti/mcu_plus_sdk/am243x/09_01_00_41/examples/drivers/boot/sbl_emmc/am243x-evm/r5fss0-0_nortos
❯ cat default_sbl_emmc.cfg
#-----------------------------------------------------------------------------#
#                                                                             #
#      DEFAULT CONFIGURATION FILE TO BE USED WITH THE FLASHWRITER SCRIPT      #
#                                                                             #
#-----------------------------------------------------------------------------#
#
# By default this config file,
# - points to pre-built flash writer, bootloader for this EVM
# - The application image points to relative path of the ipc rpmsg linux application image for this EVM
#   - Make sure this application is built before running this script
# - You can customized this config file to point to your own bootloader and/or application images
# - You can use --operation=flashverify-emmc if you just want to verify the flash contents and not flash the file.
#

# First point to sbl_uart_uniflash binary, which function's as a server to flash one or more files to eMMC
--flash-writer=sbl_prebuilt/am243x-evm/sbl_uart_uniflash.release.hs_fs.tiimage

# Now send one or more files to flash or flashverify as needed. The order of sending files does not matter

# When sending bootloader make sure to flash at offset 0x0. ROM expects bootloader at offset 0x0 of eMMC
--file=../../examples/drivers/boot/sbl_emmc/am243x-evm/r5fss0-0_nortos/ti-arm-clang/sbl_emmc.release.hs_fs.tiimage --operation=flash-emmc --flash-offset=0x0

# When sending application image, make sure to flash at offset 0x800000 (default) or to whatever offset your bootloader is configured for
--file=../../examples/drivers/ipc/ipc_rpmsg_echo/am243x-evm/system_freertos_nortos/ipc_rpmsg_echo_system.release.appimage.hs_fs --operation=flash-emmc --flash-offset=0x800000

Hi Karan

Following the method you suggested, I would encounter the following error.

Hi Karan

My board is non hsfs board (AM2434_EVM; TMDS243GPEVM) .

I tried many times, but still got the error message. What can I do to solve this problem?

Hi Weijian,

How are you generating the GP images in MCU+ SDK v9.1. The GP support has been dropped since MCU+ SDK v9.x

Hi Karan,

I made the following changes:
(1) I select the "sbl_uart_uniflash.release.tiimage" file from MCU_SDK_AM243X_08_06_00_45.

(2) I modify "makefile_ccs_bootimage_gen" in sbl_emmc_example(mcu_sdk_09_01) to generate the".tiimage" file.

Hi,Prashant

A few days ago, I received an updated AM2434-EVM, so this issue has been resolved.

Thank you for your reply.
