Frequently asked questions
Can the 512KB FLASH be partitioned for both the main application and a secure OTA bootloader?
The 512KB FLASH and 320KB SRAM are fixed on-chip resources with no external SDRAM interface on this variant. Partitioning is a firmware design decision — typical secure OTA bootloader schemes reserve 64–128KB of FLASH for the secondary-stage loader, leaving 384–448KB for the primary application. SRAM headroom for dual-buffer stacks, CANopen managers, and 24-channel 12-bit ADC DMA is application-dependent and must be validated against the compiled memory map.
