The H730 is a value-line CPU, similar to the H723/H725, but with only 128kb RAM. The FC firmware code is designed to RUN from external flash in MEMORY MAPPED mode, via OctoSPI. Use of ITCM/DTCM advised for core loops, like PID control. A bootloader is required to enable memory-mapped mode and jump to the firmware, similar to how EXST bootloader system works. Config storage is not part of this commit and is a problem when using a single flash chip in memory mapped mode because the CPU can't run read/write routines from the flash chip while writing to the flash chip. Until flash read/write routines are updated the solution requires either a second flash chip on an SPI interface, or the use of an SD card for config storage. Additional commits will support read/write of config to the code/data storage flash chip to enable cheap and space efficient single-flash-chip FC solutions. Squashed commits: STM32H730 - Workaround issue with 2GB `.elf` files being created. STM32H730 - Reduce firmware size to 1MB. STM32H730 - Add USB HS configuration. STM32H730 - Add ADC internal tag mappings. STM32H730 - Update all ADC mappings based on the referenced ST documentation. Add the VBAT channels. STM32H730 - Fix DMA continuous requests. STM32H730 - Fix ADC_INTERNAL confusion. STM32H730/G4 - Disambiguate use of ADC_CHANNEL_INTERNAL_FIRST_ID. STM32H730 - Fix documentation reference. STM32H730 - Add DMA request mapping for ADC3. STM32H730 - Explicitly set the ADC clock. STM32H730 - Configure PLL2 speeds correctly. * Tested with Ultrafast 64GB SanDisk SDXC card. STM32H730 - Use 50Mhz clock for SDXC cards. * Tested with SanDisk Ultra 64GB. 100Mhz clock gave CRC errors. STM32H730 - Ensure USB has a lower NVIC priority than the SDMMC card reads. If it's higher, 0, then the SDMMC's DMA IRQ handler doesn't get called when handing USB MSC storage reads. STM32H730 - Support CPU name in CLI. STM32H730 - Rebuild when linker scripts changes. |
