content: hi guyshere it is a pretty PowerPC7400 development board.It comes in ATX form factor with- integrated host processor MPC7400 V2.8 @ 400 MHz- 64MB @ 100Mhz Memory- Four 5V 32-bit PCI slots at 33 MHz, slot attached on Winbond W83C553F- JTAG connector on PMC module- One PMC slot on motherboard to accept processor PMC modules- Switch-selectable modes- Two standard 16650-compatible serial ports- IEEE 1284 parallel port- NVRAM and real-time clock (RTC)- Two IDE ports- LED monitors critical functions- Advanced Power Controller ("soft on/off")linux is working pretty, i can provide kernel support!about the firmware: the board has "DINK32" on flash, that firmware was developed as an internal Motorola PowerPC tool to help debug silicon as well as code. It runs on a variety of boards including the Yellowknife, Sandpoint, Excimer and Maximer. DINK32 has the full complement of commands. DINK32 supports all of the currently available PowerPC microprocessors including the 603, 603e, 604 family, the integrated processor, 8200 the 8240, the 7xx family and the 7400. DINK32 is a great source for example code when initializing the MPC105, MPC106, MPC107 memory controllers/bridge chips. DINK32 source code also includes sample code for the MPC8240 subsystems, DMA, EPIC, I2C, and I2O.You can see my ebay auctionhere

content: Quote from: gmilliorn on August 28, 2014, 02:28:09 ami need a bug fix for the firmware, it seems it has a lot of issues with pci-video board, also it has issues with dram: linux is able to see only half the physical ram because the firmware is not initializing chips in the correct wayit is not an hw issues, i have an other PowerPC PPC7400 board with the same issue.

content: Is it running DINK or uboot? If you tell me the date code I can look for later images.If it is the issue I'm thinking of, the 7400 has on-board memory instead of SODIMM,so an SPD I2C EEPROM was added which is supposed to be programmed. It is notwrite protected, so it might have been erased. Later versions of edink supportwriting arbitrary data to initialize it. Alternately, you could copy in SODIMM datayourself with uboot (i2c address 0x50).-Gary

content: The file attached is DINK 13.2 which is the last version to support Sandpoint.The workaround on your website (mi -b -w128) is the one I recalled,however the change list mentions several errata fixed in 13.1 related to that, so itmight be worth updating.-Gary
