Other Parts Discussed in Thread: TDA4VM
Hi TI Expert:
We are trying to bring up TDA4VE(J721S2) with TPS65941120, TPS65941421 & LP876411A5.
And all of these chips will take a long time for getting samples, I need to reprogram the device NVM from other TPS6594xxxx parts.
- Leo-A : From TPS65941212 to TPS65941120
- Leo-B : From TPS65941111 to TPS65941421
- Hera : From LP876411B4 to LP876411A5
Items lists below are all things I have
1. TDA4VE(J721S2) TI EVM
2. TPS6594 EVM and GUI
3. TDA4VM(J721E) System Board (base on our design and works good already)
4. TDA4VE(J721S2) System Board(base on our design and need to bring up this time)
5. 4x Bin Files from local Sales team
- PTPS65941212 PDN-0B (LeoA 3-phase) RTM-Rev 4.0_ext
- PTPS65941111 PDN-0A-0B-0C (LeoB) RTM-Rev 4.0_ext
- PTPS65941120 J7AEP-PDN-0A (LeoA) Rev3_ext
- PTPS65941421 J7AEP-PDN-0A (LeoB) Rev2_ext
Here are some problems we met & detail need to confirm:
1. Are these bin files "correct"? Or TI has some update about them?
We found that NVM setting of Bin Files are quite different to NVM setting read back from TDA4VE EVM & TDA4VM System Board. You can find the diff file in attachment.
- How can I confirm Bin Files are good?
- Which file is the 1st choice to reprogram? Bin Files from local Sales team or Bin Files read back EVM?
2. How to fix the issue EEPROM Unlock Fail issue?
We reprogramed 1212 to 1120 in TDA4VM System Board and selected not to lock EEPROM in the last step, then read back to verify. Both Bin File from local Sales team or read back from EVM works good.
but, when we solder the chip on TDA4VE System Board, we met the EEPROM Unlock Fail issue.
GUI shows that I2C Address 0x48 connected, but it is unable to read the register. And when we scan the PIMC, GUI can only find 2 of them (0x4C from 1421 and 0x58 from 11A5)
PS: We changed the I2C Address of Hera from 0x4C to 0x58 for address conflict issue.
- What‘s the reason for EEPROM Unlock Fail issue? Are some thing I need to check on TDA4VE System Board.
3. Is LP876411B4 works good for TDA4VE?
Local sales team told us that it should be good for VE. But, we found that LP876411B4 has the default I2C address 0x4C, and conflict to Leo-B. As I known, 11B4 + 1213 is good fro TDA4VM.
We also found that Bin file read from 11A5 is quite different to Bin file read 11B4, 11A5(14KB) is larger than 11B4(10KB). and it's unable to program Bin file from 11A5 into 11B4 due to oversize issue.
- Can you provide the bin file of 11A5 to us?
- Can bin file program into 11B4?
looking for you feedback
Thx!
