Read/Write to EEPROM does not work anymore, but selfboot does
I've built a custom ADAU1452 board with a Winbond W25Q SPI flash. I have used this board with no issues for the last 6 months or so but I had to reconfigure it and for some reason I can't write to the

Issue writing to eeprom
Hello, I'm going to give you a bit of my backstory to make things clearer. My dad and I like building speakers. Recently, we watched a couple of YouTube videos explaining how a DSP can have a drastic

Sigmastudio+ EVAL-ADAU1467Z write EEPROM/selfboot
Hello, what do I need to do to write the EEPROM of EVAL-ADAU1467Z with Sigmastudio+ 2.4 and USBi and get it running in selfboot mode? When I create a new project and connect the PC with USBi and the U

Write Latest Compilation through DSP / In Field Update
Hello togehter, I have a question regarding the option to write the selfboot memory through the DSP. In our setup we are connected to the ADAU1452 via I2C and the Selfboot EEPROM 25AA1044 is connect v

Writing to EEPROM does not work
Hi folks, I have similar issues as described here: Issues writing to EEPROM - Was previously working. I built my own board which is in it's core similar to the 1466 eval board. The EEPROM is of type 2

SIGMASTUDIO+ EEPROM ISSUES (ADAU1452_CS424489)
Hi everyone, Until now we have been using Sigmastudio 4.7, but after trying Sigmastudio+, and discovering it gits!, and that it has a much more usable interface, we are moving our development to the n

Selfboot
Hello, I am working with the AD2428WD1BZ, which integrates the ADAU1452 DSP. I have successfully saved a SigmaStudio schematic to the onboard EEPROM and verified that the selfboot functionality operat

Issues writing to EEPROM - Was previously working
Hello, I have build my own DSP board based off the ADAU1466 DSP. On the board I also have a EEPROM from Microchip. Its the 25LC1024T-E/SM. It is a 1Mbit SPI EEPROM. I have succesfully written a progra

Can the ADAU core write values to EEPROM? How can I write the Toggle Counter value?
Hello, I use a button to increment the index in the 'toggle counter', and this index selects the equalizer curve via 'index selectable filters'. Everything works as expected, but I don’t know how to w

E2PROM Selfboot Mode not working
Hello, I encountered a problem while trying to program the 25LC1024-1 EEPROM using our custom-designed board with the ADAU1466Z. When I attempt to load a program onto the EEPROM via the DSP using Sigm

SigmaStudio+ does not apply the “PLL Input Clock Divider” setting to the hex file, so it is not written to the EEPROM
Hello, I have again found a bug in SigmaStudio+2.3.0: SigmaStudio+ does not apply the “PLL Input Clock Divider” setting to the hex file, so it is not written to the EEPROM! Divide by 4” is always writ

ADAU1772 IC 2-WinE2PromLoader Creates 16KB File
The WinE2PromLoader tool does not auto-configure itself to the EEPROM you are using or the necessary minimum file size. The appropriate filesize is 4KB. I can go into the register control section, con

External Master Clock vs I2S
Using ADAU1772, we create a Master Clock with our fpga. It is a little off, 12.262 MHz. I did not change anything in the PLL SigmaStudio tab, wrote the EEPROM with the fpga, and we got the intended si

Self Boot from external EEPROM using SigmaStudio+
Hi, I'm using the EVAL-2428WD1BZ board (rev. 1.1) along with SigmaStudio+ (ver. 2.2.0). I've been trying to configure ADAU1452 so that it boots from an external EEPROM (24AA512) but to no avail. I can

Interface Read / Write ADAU1467
Hello together, we have a question about the Master Control Port Interface Read and Write. Our requirement is that we need to store some values, which are set during runtime of the ADAU1467, persisten

How to script in SS+ EEPROM block read/write from Python
Creating some new Python scripts for SS+ that are similar to some ones done in SS 4.7. Now that SS+ has an EEPROM block I would like the script to be able read/write it as part of the test/production

How to use EEPROM block in SS+ for an I2C part?
I have a board with an ADAU1452 and an EEPROM that are controlled via I2C from a small micro. I would like to be able to load/read the EEPROM contents from SS+, which if you go to the settings looks p

SigmaStudio+ ADAU1452 unable to write EEPROM?
Hello, I've been trying for hours to get a board with an ADAU1452 and an EEPROM (SPI on the master of the ADAU1452) to run. My problem: With SigmaStudio 4.7 everything works perfectly. With SigmaStudi

E2Prom read/write&selfboot problem.
Hi, I have a similar problem and could not figure out how to solve it. In addition to the previous question, I was also able to read the writing cycle of 1466 core via Analog Discovery logic analyser

Confusion About E2PROM and MCU
I'm trying to integrate the ADAU1702 into a project and I'm experiencing some confusion about how a permanently connected MCU and E2PROM are meant to interact, if at all. Do I need an E2PROM if I'm us

ADAU1452 suitable SPI EEPROMs
I want to go with a bigger EEPROM than what is used in the EVAL board to be safe with large FIR filters. I cannot find much information about which specifications to look for. I thought 25CSM04T-I/SN
