EVALUATION BOARD SOFTWARE
The SW driver on evaluation board can be updated using the u-boot bootloader that comes with board. However, we suggest that
customers purchase Vi+ 5.0 and a low-cost JTAG debugger for Blackfin processors (HPUSB-ICE or ICE-100B) to use in case
the u-boot software is accidentally erased or corrupted.
UPGRADING THE APPLICATION BINARY USING U-BOOT
Every EVAL-ADV8005-SMZ evaluation board ships with the U-Boot boot loader firmware. Assuming this software hasn't been
erased/corrupted, you have the option of upgrading the firmware using only an RS-232 cable and software.
The output from u-boot should look something like this:
-------------------
U-Boot 2012.07-rc2 (ADI-2012R2) (Jul 16 2013 - 11:21:16)
CPU: ADSP bf524-0.2 (Detected Rev: 0.2) (spi flash boot)
Board: ADI Advantiv™ Video Evaluation Board
Support: http://ez.analog.com
Clock: VCO: 300 MHz, Core: 300 MHz, System: 100 MHz
RAM: 8 MiB
SF: Detected M25P32 with page size 64 KiB, total 4 MiB
In: serial
Out: serial
Err: serial
KGDB: [on serial] ready
Hit any key to stop autoboot:
-------------------
If you see this RS232 output, you can use the following steps to upgrade the application binary on your board (if you determine this is
necessary). Note that these instructions assume you are using the version 4.78 of Tera Term for Windows (which is free to download and
use). We have experienced YMODEM issues with previous versions of TeraTerm, so we strongly suggest using version 4.78 or higher.
1. After you see the
hit any key to stop autoboot
prompt, press a key during the countdown. You should then see a prompt,
bfin >
.
2. At the prompt, type the following command:
sf probe 0:1
You should see the following:
SF: Detected M25P32 with page size 64 KiB, total 4 MiB
bfin>
3. At the prompt, type the following command:
loady
You should see the following output:
## Ready for binary (ymodem) download to 0x00800000 at 115200 bps...
4. In Tera Term, under
File
, click
Transfer
, then
YMODEM
, and select
Send…
5. Select the application binary file (for example,
BF_7625_8005_VSP_1.80_RC3_20140321.bin
) and click
Open
.
You should see the YMODEM send dialog box progress quickly from 0% to 100%. If the software stalls at Packet 1 or Packet 2 for a few
seconds, you may need to cancel and retry. It is possible that you may need to repeat Step 3 through Step 5 a few times to accomplish the
transfer. After the transfer is complete, you should see something like the following output:
CCxyzModem - CRC mode, 0(SOH)/721(STX)/0(CAN) packets, 4 retries
## Total Size = 0x000b3f70 = 737136 Bytes
bfin>
6. At the prompt, type the following command to erase the application area of the SPI flash memory:
sf erase 0x60000 0xc0000
(Note: that this is slightly larger than the value 0xa0000 used on previous evaluation boards)
You should then see the following output:
bfin>
7. At the prompt, type the following command to program the application area of the SPI flash memory:
sf write $(loadaddr) 0x60000 $(filesize)
You should then see the following output:
bfin>
8. At this point, if you reset your board and allow the countdown to complete, U-Boot should launch the application binary that you just
programmed.
