Hi. everybody.

I made a board for our project and purchased MiniWiggler v3.
And trying to connect these for download and debugging.
The JTAG connector was not included in the Mini wiggler, so I used the DAP.

However, our board is not recognized in DAS device scanner.
The DAS program was recently received from the website and used, and Mini wiggler's pins were connected as follows.

--------------------------------------------------
1. Vref : 5V
2. DAP1 : P10.12 of xc2786
3 GND : GND
4. DAP0 : P10.10 of xc2786
5. GND : GND
6. DAP2 : Not connected
7. Key : Not connected
8. DAP3 : /TRST of xc2786
9. GND :  GND
10. RESET : /PORST of xc2786
--------------------------------------------------

Debugger-related registers are used as default values.

Thank you.

Hi Infineon expert,

I have used Infineon ICE2HS01G for Half bridge LLC converter  for EV charger application.

Power rating is 1KW,Input is 410V DC, output is 58V,20A max.

I have followed design steps of infineon reference design of 2KW,48V Charger(LLC section only), https://www.infineon.com/cms/en/product/evaluation-boards/eval_2kw_48v_char_p7/

Converter is working good, but problem is Ripple voltage and Ripple current Requirement could not able to match.

Our requirement is 0.5V Ripple voltage and 0.5A ripple current tight regulation,for me Bridge Rectified,100HZ ripple travelled through output side as well. output side with L or without L we observe same response for 100HZ ripple

Kinldy advice me steps to follow to reduce this 100Hz Ripple(either by playing feedback path,rejecting 100HZ component in frequency response & its corresponding R,C values and High frequency ripples.I have attached circuit and output waveforms for your references

Hello,

Some boards of our last batch have problems connecting to the XE164FM. Normally we connect the miniWiggler and use Memtool to program the boards for the first time. However on the problematic boards Memtool cannot connect and DAS Basic Client says "DAS Error: DEVICE_LOCKED" and we are prompted to enter a key. We have no idea what key to enter as we have never assigned one. The device is identified as XE166/XC2000-Family.

Instead we tried to connect using the BSL/ASC mode. After making sure the configuration pins have the correct levels we were able to connect using Memtool. However all PFLASH sectors are locked and cannot be erased or programmed. All sectors execept for #15 have a blue padlock, #15 has a black one. We tried to remove protection from all sectors (and specific ones) but Memtool gave us a "Protection operation failed!" error. The Memtool log says the following:

• Couldn't disable protection ! Wrong password ?
• Couldn't disable protection ! Wrong password ?
• Error message from FLASH driver, command 'Protection':
• FLASH/OTP operation failed

Reading from the locked sectors seems to work. At least Memtool reports success.

Any ideas why this is happening? We have not locked anything. Could the XE164 be faulty? Or could any external component on the board cause problems like these? If so where should we start to look?

Hello,

SAK-XC2287M-104F80LR-AB / PG-LQFP-144-4

In below pic, some of the parts have chamfered corner  at the lower left corner (as datasheet shows) and some of the parts have it at the upper left side corner.

Is that normal?

Looking forward your early reply, thank you.
