Part Number: MCU-PLUS-SDK-AM243X
Other Parts Discussed in Thread: UNIFLASH

Hi all,

My customer wants to know if there is any flash writer for USB DFU for qspi in the SDK.

I found "mcu_plus_sdk_am243x_09_00_00_35\examples\drivers\boot\sbl_qspi", but it's empty.

Can the flash writer for ospi handle qspi cases?

Thanks,

Hang

Hi,

The USB DFU flasher is available here - https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/TOOLS_FLASH.html#TOOLS_FLASH_DFU_UNIFLASH

Here is the SBL build for the same -

The config to be used is here - tools/boot/sbl_prebuilt/am243x-evm/default_dfu_ospi.cfg

Hi Aakash,

Thank you for the information. I found that the sbl_prebuilt folder only has flasher for OSPI. Are OSPI flasher works for QSPI as well?

Thanks,

Hang.

Hi Hang Yang,

The prebuilt flasher is not a good choice for custom flashes. For custom flash integration, use this to enable the custom flash on AM243x -- https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/CUSTOM_FLASH_SUPPORT_GUIDE.html

After the flash_diag and flash_io works, you should be able to integrate flash syscfg changes in sbl_usb_dfu_uniflash example and it will be functional for custom flashes.

Hope it helps.

Best Regards,
Aakash
