AM6442: How to add a new flash device

Part Number: AM6442
Other Parts Discussed in Thread: UNIFLASH, SYSCONFIG

Hi all,

I follow the link below to add a new flash device

https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/08_00_00_21/exports/docs/api_guide_am64x/CUSTOM_FLASH_SUPPORT_GUIDE.html

but when I build the project under examples\drivers\boot\sbl_uart_uniflash\sbl_uart_uniflash_am64x-evm_r5fss0-0_nortos_ti-arm-clang,I see the errors below

I have changed the source\board\flash\flash_nor_qspi.h

What I want to ask is if I want to add a new flash device, in addition to the steps in the link above, what other changes need to be made?

Hi Ethan,

I am routing your query to our MCU experts to comment.

Hi Ethan,

First of all I assume you have done the step 1 - 4 in the guide

I think you may missed one thing in step 5 when you build the sbl_uart_uniflash:

"update the example.syscfg"

You will need to update the example.syscfg by selecting the newly created flash driver in step 2-3.

Best regards,

Ming

Hi Ming

I did update the example.syscfg,but there are indeed these errors when building

Hi Ethan,

I assume the gFlashNorQspiDeviceDefines_IS25WP032D and gFlashNorQspiAttrs_IS25WP032D are defined in your new flash driver and make sure your new driver is linked with your project.

Best regards,

Ming

Hi Ming

I have defined gFlashNorQspiDeviceDefines_IS25WP032D and gFlashNorQspiAttrs_IS25WP032D in flash_nor_qspi_device_IS25WP032D.c.

and the new flash device is selectable in sysconfig.

I would like to ask if there are any additional steps beyond those mentioned in the link

or do I have any other files that need to be modified except to change their name in flash_nor_qspi_device_IS25WP032D.c and flash_nor_qspi.h?

Hi Ming

I have resolved my problem by rebuild libraries.
