Can QSPI bootloader be set only via SD card?

Other Parts Discussed in Thread: UNIFLASH

Hi,

I use idkam437x with ccs 6.1.2 and sysbios sdk 2.1.1.2.

I would like to use QSPI bootloader in my application and have found somme QSPI booting instructions In sdk user guide, 'Flashing and Booting' section.

I would like to ask if  flashing the bootloader and application to qspi flash really needs the usage of SD card - that makes the SD port crucial in commercial projects - is there any other way of QSPI flash programming (without SD card)? 

Thank you in advance!

JJ

    Jacek,

    Please note that the utility provided in the SDK is a sample utility that demonstrates how this can be done on a reference EVM platform and is not a production solution. The utility can be used as reference to develop custom utility to read the image over USB/Ethernet and flash the custom hardware.

    Also, note we have other reference utilities like Uniflash avilable for AM437x devices that flashed the boot media over UART/USB/Ethernet however this has been tested only on AM437x EVM and not on the IDK.

    Hi Rahul,

    Thanks for your answer.

    Uniflash seems to be a good option to try, however it indeed is not supported on IDKAM437x. Do you think we can try it on this set if we change Sysboot connections? It does not seem to be a lot of work....

    Thanks,
