Florent Kermarrec	8211aca2e8	Avoid Official/Partner/Community differentiation: use same directory for all platforms/targets. ... We initially wanted to provide different level of support for the platforms/targets, mainly to avoid too much maintenance and let each contributor update its contributed platforms and targets, but it's easier to update all platforms/targets all-together when LiteX evolves or changes (and that's what has been done on litex-boards since the creation of the repository). So let just simplify things and avoid this differentiation.	2020-02-03 09:36:30 +01:00

Drew Fustini	b3f175c064	add the Hackaday Supercon ECP5 badge ... Add the Hackaday Supercon 2019 badge which has an ECP5 FPGA: https://hackaday.io/project/167255-2019-hackaday-superconference-badge These changes are from Michael Welling's fork: https://github.com/mwelling/linux-on-litex-vexriscv During Supercon, we trying two approaches: - use the built-in 16MB QSPI SRAM - use add-on cartiridge with 32MB SDRAM by Jacob Creedon We were not able to get the QSPI SRAM working so I've removed those changes, and I have just added the changes that are needed to boot Linux with the 32MB SDRAM. Thanks to Jacob Creedon, Greg Davill and Tim Ansell who helped debug. KiCad design files for the SDRAM cartridge are available at: https://github.com/jcreedon/dram-cart/ The SDRAM cartridge PCB is shared at: https://oshpark.com/shared_projects/IQSl2lid More information in this blog post: https://blog.oshpark.com/2019/12/20/ The Hackaday Supercon badge PCB design is here: https://github.com/Spritetm/hadbadge2019_pcb	2020-01-06 16:59:15 +01:00
