Other Parts Discussed in Thread: TPS25751
Tool/software:
Hello, I hope you are doing well.
I’m writing this post because I have a couple of doubts regarding the EEPROM update process using the TPS with a new patch bundle.
The first one is: what is the correct parameter that should be written into DATA1 before executing an FLvy command? In Step 3 of the guideline TPS25751 and TPS26750 EEPROM Update Over I2C, it mentions writing the region start into DATA1, but I don’t understand if this refers to the new region start, the old region start, or something else. And it also calls my attention that after that, it executes again the command FLvy but with null input. Why is it needed to execute the command twice?
Finally, I would like to know what happens if, instead of performing the update as suggested in the document, the entire EEPROM content is simply rewritten from scratch using FLwd. From a technical point of view, this seems possible, but no document explains why this approach should not be used.
Thank you in advance
Francisco
