I recently found this:
https://brtchip.com/wp-content/uploads/2024/04/Errata-notification-2024-R2.pdf
It states:
"We are reaching out to notify an important Errata that has been identified on our BT81x / BT88x series. This
Errata pertains to specific user applications, which may affect the functionality or performance of the product
under certain conditions."
What this does not state is what the actual issue might be.
So, what is it?
Given the date of release this could appear in a version of BT81X programming guide later than 2.4.
But I don't see anything in the 2.5, 2.6 or 2.7 history that indicates an issue.
I vaguely recall seeing extra DISPLAY commands added to the end of the command list to address some issue, is this related to this erratum?
This seems important... so I am boosting this post.
Hello,
Details of the Errata can be found in the following Technical notes:
BRT_TN_005_BT81x_Errata_Technical_Note (https://brtchip.com/wp-content/uploads/2024/04/BRT_TN_005_BT81x_Errata_Technical_Note.pdf)
BRT_TN_006_BT88x_Errata_Technical_Note (https://brtchip.com/wp-content/uploads/2024/04/BRT_TN_006_BT88x_Errata_Technical_Note.pdf)
best Regards

Thanks, so it was the "Display list instruction overfetch".
I even already had BRT_TN_005_BT81x_Errata_Technical_Note.pdf.
I just was not looking under https://brtchip.com/document/technical-notes/ , maybe add (Errata) to that one as well?
Oh, and another small thing, "Programming and User Guides" is sorted by date, newest on top, could that perhaps be done on "IC Data Sheets" and "Application Notes" as well?
Ok, this could answer to this topic: http://www.brtcommunity.com/index.php?topic=428.msg2117#msg2117 (http://www.brtcommunity.com/index.php?topic=428.msg2117#msg2117)
I've seen that issue is resolved in new version of ESD in Esd_Render function.
