Question

Can I increase the flash memory of STM32G030K8T6 with SPI NOR Flash memory?

Hello,

I am trying to use a 240x320 ili9341 screen with g030 but even one picture doens't fit into flash memory. (If you are familiar with ILI9341, the picture I am talking about is snow_tiger)

I made some research on it and saw that in TouchGFX website  STM32G071 nucleo board with the X-Nucleo-GFX01M1 expansion board is used. The expansion board has 64-Mbit SPI NOR Flash memory.

If I buy a NOR Flash memory, can I overcome my problem?

Thank you

I tried using SD Card but when I imported FATFS middeware on CubeMX, RAM overflowed :(

It doesn't provide for a QSPI interface, so can't be mapped into the processors memory space, or allow for Execute-In-Place.

SPI access should be viable, and have a relatively small code foot-print.

You could page data and code into RAM.

You can add SPI memory, but with 8kB RAM i mean you waste time with 030 try work with graphics. Why not start with other?
