I have a big array for my OLED display, but Keil cannot build it.
is there any method? I have an external 1M SPI FLASH on my board.

Hi daniel59,
Could you please clarify if you mean ROM or RAM? Because you are not able to download firmware into the ROM. I am not able to understand your question, do you mean to program the SPI Flash and boot from there? Also, which is the length of your project? The available memories blocks of DA14580 for downloading firmware are the system RAM, the OPT. and an external SPI flash, as in your case. For getting more information about the memories DA14580 chip, please check the datasheet. You can use the Smart Snippet toolbox in order to program the SPI Flash from the SPI Flash/EEPROM tab. Be aware that you can download firmware into SPI Flash either through JTAG or through UART interface. Please read the section 11 SPI Flash Programmer of theUM-B-083 SmartSnippets Toolbox User Manualuser manual. You can download it from the Software&Tools tab of DA14580 chip from our support page. If you have not downloaded the Smart Snippet, you can download it from the Tools windows of Software&Tools tab. Could you please let me know which SPI Flash are you using?
Thanks, PM_Dialog
No, that is not my question.
my code now have a big array, when i build my code, keil shows:

But if i separate the array into 2 arrays, it can be build.
I think it means my array is too big for DA14580's RAM, so can I put that array into SPI FLASH?
My FLASH is w25x10cl.
Hi daniel59,
Apologies but didn’t understand exactly your question. Yes, that’s correct, the array is probably too big for DA14580's RAM, so you should put into the SPI Flash. If you are not aware how to use the SPI flash driver, please check the SPI Flash Memory Example of the SDK. This example demonstrates how to initiate, read, write and erase an SPI Flash memory using the SPI Flash driver. The project is located in the projects\target_apps\peripheral_examples\spi\spi_flash SDK directory.
Thanks, PM_Dialog
