AM2434: am2434

Part Number: AM2434
Other Parts Discussed in Thread: UNIFLASH,

Tool/software:

hi all

I am looking for an example of how to program a multicore application into the on-board SPI flash on the AM2434-LP.

I tried working with the Uniflash tool, but I noticed that the sbl_qspi_multicore_elf directory in SDK 10.01.00 is empty.

Could you please provide guidance or an example?

best regards

To develop multicore application, please get started by referring this: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1394609/faq-processor-sdk-am64x-how-to-do-ipc-communication-with-only-two-cores-say-r5fss0-0-and-r5fss1-1?tisearch=e2e-sitesearch&keymatch=faq%3Atrue

Dear Vaibhav,

You didn’t answer my previous question, but I was able to resolve those issues on my own and now my multicore application is running correctly.

I now have another question: how to build a multicore image and program it into the SPI flash.

Here is my current attempt using MulticoreImageGen.exe with a batch file:

Unfortunately, this does not generate a valid image for my 3 cores.

I also tried working with UniFlash, but I am still unsure if this will fully solve my problem.

Could you please provide guidance or an example on how to correctly build the multicore image and burn it to the onboard SPI flash for the AM2434-LP?

Thanks in advance,
Baruch

Do you want me to also add a reference to the empty sbl_qspi_multicore_elf directory in SDK 10.01.00 (like you mentioned earlier today), so TI understands what’s missing from their SDK?

The example which you mentioned has not being given out for AM243-LP as you also mentioned, but you could take a reference from here:

Please share this, thank you.

cd C:\am2434\tools MulticoreImageGen LE AM2434 app_multi_core.appimage ^ agg_main_r5fss0-0_freertos_ti-arm-clang1.rprc ^ agg_r5fss0-1_nortos_ti-arm-clang.rprc ^ agg_m4fss0-0_nortos_ti-arm-clang.rprc

Are you referring the command mentioned in the MCU+ SDK? https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/latest/exports/docs/api_guide_am243x/TOOLS_BOOT.html#MULTICOREIMAGEGEN_TOOL

Looking forward to your response.

Best,
