TMS320F28P550SJ: error trying to load code into flash usign sci

Hi Ari,

Are you using the serial flash programmer tool?

Thank you,

Luke

Hi, Luke

yes, I'm using the serial flash programmer tool located at: C:\ti\c2000\C2000Ware_5_02_00_00\utilities\flash_programmers\serial_flash_programmer

Recently I tested the firmware upgrade using the C2prog app. With C2prog it worked without problems, and with the advantages of not having to compile the kernel and being much faster.

Still, I would like to know why it isn't working with the serial_flash_programmer.

Hi Ari,

The F28P55x SCI flash kernel project uses the 512-bit programming feature of the corresponding Flash API. Thus, the application sections stored in flash memory need to be aligned to 512-bit boundaries. Please add "ALIGN(32)" to any memory sections stored in flash. Please see section 5.4 of this document for more details.

Kind regards,

Skyler

Hi Skyler,

I'm using the "f28p55x_flash_ex3_sci_flash_kernel" example as the kernel, so I need to add the align(32) command to the application and not to the kernel. Correct?

Where exactly in my application code do I need to include the align(32) command?

Ari.

Hi Ari,

Yes, you need to add it to the linker .cmd file of the application, not the kernel. For an example, take a look at C2000Ware_5_02_00_00\device_support\f28p55x\common\cmd\28p55x_flash_api_512bit_lnk.cmd

Kind regards,
Skyler

Skyler,

I used aligh(32) in my application's .cmd file and there is still an error.

I don't understand why the serial_flash_programmer.exe program doesn't work like C2Prog, being able to use the .out file directly, without needing to configure and compile a kernel for my board, and without needing to configure my application to work with it.

C2prog loads the entire firmware in less than 10 seconds, just by pressing a button, as the GUI maintains the path from the last time I loaded the .out file.

I give up trying to load the firmware with serial_flash_programmer.exe, I'm going to stick with C2prog.

Thank you for your help,
Ari

Hi Ari,

Are you able to provide your linker cmd file here for review? Can also accept through direct message.

Thanks and regards,
