Unknow Flash in DSR410DNA

Post by Pichardo » Wed Jun 13, 2012 12:08 pm

I have a receiver model DSR-410DNA. Selecting DSR405 in the config work fine to read the flash, this is my register view.

Code: Select all

D0= 0004E85C   D1= 3ADAB84F   D2= FFFFFFFF   D3= FFFFFFFF   
D4= FFFFFFFF   D5= 5C37E280   D6= FFFFFFFF   D7= FFFF0000   
A0= FFFFFA4E   A1= FFFFFFFF   A2= 60C68032   A3= A1C6B9E9   
A4= FFFFFFFF   A5= FFFFFFFF   A6= FFFFFD28   A7= FFB5FF00   

RPC  = 000002BE   PCC  = FFFFFFFF   SR   = 00002700   USP  = 96714A41   
SSP  = 99999999   SFC  = 00000005   DFC  = 00000005   ATEMP= 00000005   
FAR  = 00FFFA76   VBR  = 00000000   
I can read a whole plash or separe as boot, plat, app and the nvram too.

But my problem is when i try to "write"

It not detect the flash.. all i got is this

Code: Select all

-flshdct 0
[color=red]Unknown flash type![/color]

The flash is

AM29F400AB

I include the datasheet here.

I add this in the flash.xml file to include the new flash

Code: Select all

		<flash>
			<id1>0x1</id1>
			<id2>0x22AB</id2>
			<name>AMD AM29F400AB</name>
			<size>0x80000</size>
			<protocol>0</protocol>
			<block>
				<secnum>1</secnum>
				<secsize>0x4000</secsize>
				<secnum>2</secnum>
				<secsize>0x2000</secsize>
				<secnum>1</secnum>
				<secsize>0x8000</secsize>
				<secnum>7</secnum>
				<secsize>0x10000</secsize>
			</block>
I appreciate a lot any help in this . . .

What I need to do to be available to detect and write the flash ?

Keep Trying . . . !

This could mean your write of the flash is disabled in hardware. When detect flash you need to be able to write certain command to the flash and read back.
