Part Number: TAS5782MEVM
I am very confused by what is required to successfully generate characterisation file which can be applied to the TAS5782EVM for use in Smart amp processing.
Initial assumption is that Learning board 1 (LB1 / PP-SALB-EVM) is needed as it lists TAS5782 as compatible hardware. http://www.ti.com/tool/PP-SALB-EVM
Is it the case that PP-SALB-EVM is stand alone hardware i.e. connect Mic and speaker to - PP-SALB-EVM then connect to the PP-SALB-EVM via USB using PPC3 running on Windows Machine? Nothing else needed?
Using the setup process in Learning Board software, a characterisation file is generated that can then be loaded into the TAS5782 EVM software running on PPC3? (obviously PP-Motherboard Console and TAS5782MEVM hardware required).
(I had been confused by this because despite the list of supported EVM board at the top of the PP-SALB-EVM page, namely (TAS5825MEVM, TAS3251EVM, TAS5782MEVM, TAS5766MDCAEVM) , when you read the rest of the webpage only two devices are cited
" Works with these devices: TAS5766MRMT (QFN) and TAS5766MDCA (TSSOP)". And when reading the user guide (REV D). Different sets of devices are listed as target hardware with no further mention of the initially stated compatible hardware).
My Problem is that I have TAS5782EVM as well as DV stage builds of a product including TAS5782, but PP-SALB-EVM is no longer in production - I may be able to borrow one of these from a colleagues, but am also searching for alternatives.
If I was to have PP-SALB2 -EVM - (LEARNING BOARD 2) as well as one of the compatible EVM modules. ( TAS2555YZEVM, TAS2557EVM and TAS2559EVM.)
Then could I use the characterisation file generated to load into TAS5782 EVM? Or are the characterisation files from PP-SALB-EVM and PP-SALB2-EVM different in some way that makes them incompatible?
Just for clarity I understand the set up of PP-SALB2-EVM to be as follows:
Connect Target EVM board and PP-SALB2-EVM using ribbon cable and 34pin header on both boards, Microphone, Laser and adaptors also connect to PP-SALB2-EVM. Then PP-SALB2-EVM connects via USB to PPC3 on computer. (PP-Motherboard- not required)?
A1: Yes you are correct TAS5782 is supported by PP-SALB-EVM and nothing else is needed. The FAE you are working with has reached out to us as well and is trying to find a PP-SALB-EVM for you as well.
A2: The characterization files from PP-SALB2-EVM are not currently compatible with TAS5782. TAS5782 is an older device and in turn the application is also older so it is not currently compatible. We are working on this upgrade. PP-SALB2-EVM should be connected to the compatible EVMs (TAS2555YZEVM, TAS2557EVM and TAS2559EVM) not the TAS5782. PP-SALB2-EVM uses ribbon cable and 34pin header on both boards, Microphone, Laser and adaptors also connect to PP-SALB2-EVM. Then PP-SALB2-EVM connects via USB to PPC3 on computer. No PP-MB required.
The TAS5825M, a newer device, is compatible. We suggested this solution to the FAE, who said this would not work for you since this is a DV build.
All the best, Carolina

Thank you for your answer and to check my understanding.
TAS5825MEVM can receive a characterisation file either from standalone PP-SALB-EVM .... or...... PP-SALB2-EVM + (compatible EVM module connected via ribbon cable).
TAS5782MEVM can only receive characterisation file from PP-SALB-EVM!
Although we are about to enter DV we are considering a switch if we cannot acquire PP-SALB-EVM - as such your FAE in Taiwan is sending PP-SALB2-EVM + TAS2557EVM in order that we can evaluate, TAS5825MEVM which I also have on order.
Thanks for your help.
In reply to Edward Rose:
Yes that is correct.
Hello Ed Rose,
Good news! Our PPC3 team was able to update the TAS5782 application to support the import from PP-SALB2!
Please see the standalone PPC3 app in this link: https://txn.box.com/s/a2j3z3fnzynmler4ewul0vatit3alvsp
All the best,Carolina
Thanks this is great news!
Do I need to use an EVM module with the PP-SALB2-EVM? to get this to work? - I have TAS2557EVM.
Yes the PP-SALB2-EVM should be used with TAS2557EVM, as shown in the image below:
