From 9e443621796a150b244d49a784b77c744ea04d94 Mon Sep 17 00:00:00 2001 From: Sergey Vlasov Date: Fri, 12 Aug 2022 00:37:41 +0300 Subject: Add minimal STM32F103C6 support (#17853) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Unfortunately, the crippled versions of “Bluepill” boards with STM32F103C6xx chips instead of STM32F103C8xx are now sold all over the place, sometimes advertised in a confusing way to make the difference not noticeable until too late. Add minimal support for these MCUs in the common “Bluepill with stm32duino” configuration, so that it could be possible to make something useful from those boards (although fitting QMK into the available 24 KiB of flash may be rather hard). (In fact, I'm not sure whether the “STM32” part of the chip name is actually correct for those boards of uncertain origin, so the onekey board name is `bluepill_f103c6`; another reason for that name is to match the existing `blackpill_f401` and `blackpill_f411`.) The EEPROM emulation support is not included on purpose, because enabling it without having a working firmware size check would be irresponsible with such flash size (the chance that someone would build a firmware where the EEPROM backing store ends up overlapping some firmware code is really high). Other than that, enabling the EEPROM emulation code is mostly trivial (the `wear_leveling` driver with the `embedded_flash` backing store even works without any custom configuration, although its code is significantly larger than the `vendor` driver, which may also be important for such flash size). --- .../boards/STM32_F103_STM32DUINO/ld/STM32F103xB_stm32duino_bootloader.ld | 1 + 1 file changed, 1 insertion(+) (limited to 'platforms/chibios/boards/STM32_F103_STM32DUINO/ld/STM32F103xB_stm32duino_bootloader.ld') diff --git a/platforms/chibios/boards/STM32_F103_STM32DUINO/ld/STM32F103xB_stm32duino_bootloader.ld b/platforms/chibios/boards/STM32_F103_STM32DUINO/ld/STM32F103xB_stm32duino_bootloader.ld index dc47400dc5..3a47a33156 100644 --- a/platforms/chibios/boards/STM32_F103_STM32DUINO/ld/STM32F103xB_stm32duino_bootloader.ld +++ b/platforms/chibios/boards/STM32_F103_STM32DUINO/ld/STM32F103xB_stm32duino_bootloader.ld @@ -18,5 +18,6 @@ * STM32F103xB memory setup for use with the STM32Duino bootloader. */ f103_flash_size = 128k; +f103_ram_size = 20k; INCLUDE stm32duino_bootloader_common.ld -- cgit v1.2.3
