Interface write block causing boot failure

Question

Hi everyone, 
 I'm working with a project that need change between 3 inputs, so I'm using a rotary encoder to do this job. 
 The problem it's when I use a Interface Read/write block to save on my EEPROM the state of the rotary, next reset the DSP doesn't boot. 
 
 I think it's a checksum error, like the EEPROM values changed (because the iface write block), the checksum it's not updated accordingly. 
 I read on another three posts that can be work using a ABCD block, or write 0x00 on the last 8 bits of the EEPROM code... Nothing worked. 
 
 Think it's a bug? Because DaveThib said the last sigmastudio version, when use a InterfaceWrite block, the software already change the checksum to all 00, and disable this function. 
 It's not working for me. 
 
 The program:

The program its attached too, with all XML files. 
 
 Thanks by advance. 
 
 Ps.: DSP: ADAU1466, EXPANDER: PCA9536, MEMORY: 24AA512 I2C. SIGMASTUDIO ICARO.rar

Hello IcaroViana2, 
 
 I tested this and initially it didn't work for me as well. However, when I did the changes given in this post, it comes out to be working well. I guess you already read the post, have you done the same thing mentioned in that post and still facing issues? I hope you have written the zeros in the correct place. The above-mentioned post has a very detailed explanation of how to do this.

 This must be last 8 bytes which is the checksum. I guess you had a typo, yet make sure that you write it in the correct place. 
 Please try this and get back.
