| MIPS Boston Development Board | |
| --------- | |
| About | |
| --------- | |
| The MIPS Boston development board is built around an FPGA & 3 PCIe controllers, | |
| one of which is connected to an Intel EG20T Platform Controller Hub which | |
| provides most connectivity to the board. It is used during the development & | |
| testing of both new CPUs and the software support for them. It is essentially | |
| the successor of the older MIPS Malta board. | |
| -------- | |
| QEMU | |
| -------- | |
| U-Boot can be run on a currently out-of-tree branch of QEMU with support for | |
| the Boston board added. This QEMU code can currently be found in the "boston" | |
| branch of git://git.linux-mips.org/pub/scm/paul/qemu.git and used like so: | |
| $ git clone git://git.linux-mips.org/pub/scm/paul/qemu.git -b boston | |
| $ cd qemu | |
| $ ./configure --target-list=mips64el-softmmu | |
| $ make | |
| $ ./mips64el-softmmu/qemu-system-mips64el -M boston -m 2G \ | |
| -bios u-boot.bin -serial stdio | |
| Please note that QEMU will default to emulating the I6400 CPU which implements | |
| the MIPS64r6 ISA, and at the time of writing doesn't implement any earlier CPUs | |
| with support for the CPS features the Boston board relies upon. You will | |
| therefore need to configure U-Boot to build for MIPSr6 in order to obtain a | |
| binary that will work in QEMU. | |
| ------------- | |
| Toolchain | |
| ------------- | |
| If building for MIPSr6 then you will need a toolchain including GCC 5.x or | |
| newer, or the Codescape toolchain available for download from Imagination | |
| Technologies: | |
| http://codescape-mips-sdk.imgtec.com/components/toolchain/2015.06-05/ | |
| The "IMG GNU Linux Toolchain" is capable of building for all current MIPS ISAs, | |
| architecture revisions & both endiannesses. | |

| TODO | |
| -------- | |
| - AHCI support | |
| - CPU driver | |
| - Exception handling (+UHI?) | |
| - Flash support | |
| - IOCU support | |
| - L2 cache support | |
| - More general LCD display driver | |
| - Multi-arch-variant multi-endian fat binary |
