Can DS100DF410 load configuration via an external EEPROM without host device?
The system only contains a DS100DF410 and a EEPROM(AT24C08A).
The chip outside:
EN_SMB = Float for master mode
READ_EN: From high to low (CPLD to control the voltage change)
Hi Michael,
Thank you very much for your detailed answer.
I also have some questions about it 。 My system contains one DF410 and one EEPROM .As shown in figure 1.There is no SDA and SDC signal(SDA and SDC is always keep high).
Is it can work normally? I found this description in the Datasheet,As shown in figure 2.Is it means I should give system a cpu (Mcu) to set its register(0x05 ,bit7)?

Hi Michael,
Thank you again for your reply！
It is my fault to measure SDA/SDC signal . Now,DF410can load something from EEPROM ( EEPROM is work on ) . However , SFI signal didn't output .
------------------------------------------------------------------------------------------------------------------------------------------------
CPU configuration file:
----------------------------------------------------------------------------------------------------------------------------------------------
//Wait for 1 second//
----------------------------------------------------------------------------------------------------------------------------------------------I used scope and Logic analyzer measure the SDA and SDC ,we found the DF410 only read a part of configuation(hex file :Read from start to 394100) from the EEPROM (AT24C08D).
Could you pls help to check why the DF410 not read the whole configuation.()
You can use this tools to open file(untitled1.logicdata) .

Hi Michael
1.I upload the schematic of my setup and nothing connected to the SMBus line.(Only EEPROM).(file:SCHEMATIC1 _ 07_SFI_Repeater.zip)
2.This step is fine .It is DS100DF410 not DS110DF410 .
3.I sure it is DS100DF410 and I upload it's pic.In Slave Mode,it is the CPU configuration. I have a question to the CDR.(This is the only difference This is the only difference CPU configuration(In Slave Mode) and .Hex file (In Master Mode).)
In Slave Mode ,CPU can program DS100DF410 Reg 0x0A (0x1C).Is it necessary to program Reg 0x0A?If it is necessary ,what should I do?

CPU configuration file:
----------------------------------------------------------------------------------------------------------------------------------------------
//Wait for 1 second//
----------------------------------------------------------------------------------------------------------------------------------------------4.Yes , I have measured the ALL_DONE and ALL_DONE has been pulled low . It should havefailed , because no signal output .
I have tried it , but ALL_DONE# pin is low .

Hi Michael
I do as you say to change some Settings.I have a few problems.
1.I used my SigCon to generate hex file and DF41 always read not accurate configuration data;
2.I used your hex file downloaded to the EEPROM and DF410 can accurately read the configuration data, but DF410 output nothing.
3.I compared the (Datasheet) the default value of the register and (SigCon) the default value of the register and I found some different things. (I didn't set those registers).
File :different.rar
4.I found another problems of SigCon software.It is not reversible, when I use SigCon modify your hex file.(when i modify EEPROM>256? and common channel or Enable CRC, If I choose Add map enable ,Add 0x4 always is 0x33)
Can you give me your software download address
You can see the changes in fig. 1,fig.2,fig.3
