Hashrate:

  Hashrate: 3.5Ths ± 5%
    '''3.5T (+-5%)'''
+
  Power Consumption: ≈ 1050 Watt (with assumption of 90% power conversion ratio)
+
  Overclocking: Support automatically optimizes frequency, no need to overclock manually.
Power consumption:
+
  PSU ouput pin: 4 x 6PIN PCIe power connector.
    990W (measure on 12V port of the device)

  Controller: Raspberry Pi (version B or B+) Raspberry Pi 2 is not supported yet.

  Net weight: 4.8kg
+
  Gross weight: 5kg
Overclocking:
 
    Support automatically optimize frequency, no need to overclock manually.
 
 
PSU output pin:
 
    4x6PIN PCIe power connector. *All must be connected.*
 
 
PSU requirements:
 
    Minimum 1100W output, recommend to use high-quality PSU for server
 
with more than 1200W output and high quality power cable.
 
    Input voltage no lower than 11.7V and no higher than 12.2V (numbers
 
take from the controller)
 
    Lower voltage leads to lower hashrate and higher voltage leads to
 
possible device burning down.
 
    NOTICE: Poor quality cable may result in low voltage.
 
 
Fan:
 
    Specs: 12038
 
    Current: between 1.6A and 2.8A.
 
    Minimum RPM: 3800.
 
    *NOTICE* If the fan is broken or the fan's RPM cannot be measure,
 
the device will not start.
 
 
Controller:
 
    Raspberry Pi (version B or B+)
 
    Raspberry Pi 2 will be supported at the middle of December 2015
 
    Each Rpi can control approximately ~12 devices.
 
 
AUC:
 
    Each AUC can connect up to 6 devices.
 
 
Dimensions:
 
    354x136x150mm
 
 
Net weight:
 
    ~4.8kg
 
 
Protection Degree:
 
    IP20

DFU Updata Process Diagram

UpdataProcess.png

Judge Updating Program Or Application Program

I used a updata flag which is a four bytes word and is writed at fixd flash address (0x8000 - 4)
The flag's value is 0xAABBCCDD
When the bootloader program run, first it judge the updata flag, if the updata falg is not equal 0xAABBCCDD, it will jump to application program.
Otherwise it will run to updata program.

Jump To Application Program

When we don't want to updata application program, the bootloader program should run to application program.
In order to achieve this goal, we can add under code in your bootloader program.
asm volatile("ldr r0, =0x4000"); //"the 0x4000 is my application program's MSP point, you must change it adapt to your"
asm volatile("ldr r0, [r0]");
asm volatile("mov sp, r0");
    
asm volatile("ldr r0, =0x4004"); //"the 0x4004 is my application program reset-function entry address, you must change it adapt to your"
asm volatile("ldr r0, [r0]");
asm volatile("mov pc, r0");

Modify dfu-util For Ubuntu 14.04

#Inside your home directory, download dfu-util
git clone git://git.openezx.org/dfu-util.git
cd dfu-util
wget https://raw.githubusercontent.com/Johnson-Fan/Avalon-USB-converter/master/patches/001-add-milli_sleep.patch
patch -p0 < 001-add-milli_sleep.patch
./autogen.sh
./configure
make
The resulting binary is dfu-util/src/dfu-util.

Add DFU In AUC2 Firmware

Modify The AUC2 Firmware Flash And RAM Address

1. We modify the Flash start address at 0x4000, because the bootloader's size is 0x4000.
2. We modify the RAM start address at 0x10000200, because we remap the NVIC table at the RAM 0x10000000, and the NVIC table size is 0x200 bytes.
3. We modify the *.ld file. And my *.ld file is avalon-usb-converter.ld, you can find your *.ld file.

Remap The NVIC Table

1. Add Under Function Code In Your Program.
   /* copy the nvic table to ram */
   static void copy_nvic_to_ram(void)
   {
       volatile uint32_t *dst, size;
       volatile const uint32_t *src;
src = (volatile uint32_t *)APP_START_ADDR;//APP_START_ADDR Is The Application Program's Start Address. dst = (volatile uint32_t *)RAM_START_ADDR;//RAM_START_ADDR Is The RAM Start Address. size = NVIC_TABLE_LEN >> 2;//NVIC_TABLE_LEN Is The NVIC Table's Size. do { *dst++ = *src++; } while (--size);
/* NVIC remap to RAM */ Chip_SYSCTL_Map(0x01);
}
2. Config The Register To Remap NVIC Table To RAM

Issues

1. About Bootloader USB Descriptor:

Note the DFU Functional Descriptor' wTransferSize size, It must equal the USBD_DFU_INIT_PARAM_T's wTransferSize.

2. About IAP Transmission Data Size

The data size should be 256 or 512 or 1024 or 4096 Bytes.

3. About IAP Transmission Data Address

The data address should be a 256 byte boundary.

3. Why sometimes updata failed ?

Now, I didn't find the real reason. But, I think the reason is the time of communication is not correct. 

3. Why sometimes updata finished, but the program don't run normally ?

I think that I didn't check the flash address and the data address are right.
I will add the check in the program later.
