Other Parts Discussed in Thread: TPS92520EVM-133
Tool/software:
We are preparing to implement Daisy chain.
Use the EVAL Board to verify that Daisy chain is possible.
Currently, SPI communication is not possible with EVAL Board as well as Daisy chain.
Please check which one is wrong.
1. H/W in use
- LEDMCUEVM-132(PSIL132A) + TPS92520EVM-133(PSIL133A)
2. UI in use
-
3. SPI test using 1 and 2
- Is SPI communication possible with this UI program?
- An error bit occurs when SPI communication is performed.
- Daisy chain is not available.
- Device : 520
Comm Type : Single
Register Address : 0x00
Write Data :
Data Read : 0xFF
If you receive that information by Tx
SPI command completed successfully.
SPI Error bit set on read response.
SPI Read Response reserved bits were not '1100'.
TPS92520 PC bit is '1'.
TPS92520 TW bit is '1'.
TPS92520 read data: 0xFF.
SPI Status responds as a failure.
4. There is no Daisy chain-related manual or guide, so it is impossible to check.
- Please explain in as much detail as possible how we can test SPI Daisy Chain with EVAL Board.
Please let me know the e-mail address to send the data organized by PPT to the support team.
I'd like to deliver a organized inquiry.
