Re: Realtek 晶片刷機詢問
我昨天就找到方法了,想說試成功在PO上來,可是找的FW都不能用,最後板子被我搞死了,今天想辦法修。
底下用bootload upgrade的方法,不過它是教upgrade bootload/cfe,不是FW。
至於upgrade FW只要把其中起始位置是0改為20000即可。
bootloader Command:flw 0 80500000 1123
FW Command:flw 20000 80500000 55FEEE
原文如下:
Burn boot code image to Realtek EV board
- Use a RS232 cable to connect COM port between a LINUX PC and EV board.
- Connect LINUX PC Ethernet port to the LAN port of EV board. Set PC IP
address to 192.168.1.x (e.g., type 'ifconfig eth0 192.168.1.1').
- Start a COM port console (e.g., minicom), and set COM port setting to
38400, 8N1 and no flow control.
- Power on EV board, and press 'ESC' key in COM port console to escape the
booting process. If ok, you may see "
- Start a TFTP client in LINUX PC, and connect to 192.168.1.6. Set file
type to binary mode, and put boot file (boot) to TFTP server of EV
board.
- After TFTP upload is completed, you may see a message in COM port
console as "**TFTP Client Upload File Size = 0000xxxx Bytes at 80300000".
"0000xxxx" and "80300000" indicate the hex value of upload file size and
memory address stored image respectively.
- Type command in COM port console as "flw 0 80300000 xxxx" to write upload
image to flash address "0" from SDRAM address "80300000" with size "xxxx"
in hex.
- Then that, you may see a message shown in COM port console as:
"Flash Program from 80300000 to 00000000 with 0000xxxx bytes ?
(Y)es, (N)o->". Type 'y' to confirm the writing. After the updated is
completed, you could power off/on the EV board, and the new boot code
will be effective.
