[feature] Ability to flash F7 devices when in dual-bank mode

5

I'm working on a project using the STM32F779. We want to be able to use a bootloader to switch between flash banks bank_1 and bank_2. I can use the latest...

init_array is a technique used by gcc to construct a list of pointers to functions that should be run just prior to calling main(). This is used in C++ to...

Add the ability to insert boot methods to the BIOS's bootlist, from an external library

Background : I want to add a SPI Flash boot using my own bit-banged interface to a SPI Flash, not using the current Litex SPI Flash driver. The only way...

The ColorLight i9 v7.2 is very similar to the i5 v7.0. See https://github.com/wuxx/Colorlight-FPGA-Projects/blob/master/colorlight_i9_v7.2.md for the hardware description.

Added XC6SLX16 PiSwords dev board

1

I bought a Spartan-6 dev board as it has the same FPGA (LX16) I'm using for another project. I've tested the LEDs, Buttons, UART and SPI FLash. There are schematics...

replace void* types with typedef

2

The const char * const type can be defined as a typedef to simplify the code. This would remove the void* casts.

LiteDRAMDMAWriter sinks data when not enabled

2

The sink Stream in LiteDRAMDMAWriter has the 'ready' flag set by default. If with_csr is set, shouldn't the 'sink.ready' flag only be set if the 'enable' bit is set in...

tang_nano_9k.py toolchain_program() writes to RAM not Flash

2

The default toolchain_program() for https://github.com/amaranth-lang/amaranth-boards/blob/main/amaranth_boards/tang_nano_9k.py uses openFPGALoader. It lacks the "-f" option that writes to flash, so only programs the RAM. If you want persistent FPGA programming you need the...

Documenting LVDS input pairs
