DFU Updata Process Diagram

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.

Before Modification

After Modification

MEMORY { /* Define each memory region */ MFlash32 (rx) : ORIGIN = 0x0, LENGTH = 0x8000 /* 32K bytes */ RamLoc4 (rwx) : ORIGIN = 0x10000000, LENGTH = 0x1000 /* 4K bytes */ RamUsb2 (rwx) : ORIGIN = 0x20004000, LENGTH = 0x800 /* 2K bytes */ } /* Define a symbol for the top of each memory region */ __top_MFlash32 = 0x0 + 0x8000; __top_RamLoc4 = 0x1000000 + 0x1000; __top_RamUsb2 = 0x20004000 + 0x800;

MEMORY { /* Define each memory region */ MFlash32 (rx) : ORIGIN = 0x4000, LENGTH = 0x4000 /* 16K bytes */ RamLoc4 (rwx) : ORIGIN = 0x10000200, LENGTH = 0xe00 /* 3.5K bytes */ RamUsb2 (rwx) : ORIGIN = 0x20004000, LENGTH = 0x800 /* 2K bytes */ } /* Define a symbol for the top of each memory region */ __top_MFlash32 = 0x4000 + 0x4000; __top_RamLoc4 = 0x10000200 + 0xe00; __top_RamUsb2 = 0x20004000 + 0x800;

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

More See UM10462 LPC11U3x/2x/1x User manual,At The Page 22.

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.

TODO

1. Upgrade OpenWrt branch to master
2. Commit cgminer package for OpenWrt packages

Known Issues

1. MM can be upgrade by mismatch firmware.
2. local hashrate (GHS av) cann't match with the pool's hashrate

FAQ

1. How to deal with the red blinking machine?

2. How to boot the machine or hashboard unit safely?

3. AUC always appear and then disappear in CGMiner status ?

 It maybe damaged. Take a new one instead.
