STM32-P107

Hello,

for stm32-p107 rev b

I can not find the jumper
PWDW_D
When is closed – disables Ethernet transceiver (STE101P) Power Down Mode. STE101P
is active.
Default state is closed.

thank you

The user manual shows that in later board revisions Olimex changed the Eth. part so I suspect the jumper was deleted then.

I want to be sure that the jumper is removed.
Because I can not initialize the ethernet part.

[JohnS]

The Rev B schematics show the changed Ethernet chip and no jumper.  Are you using code suitable for the change?

The original code is written for the STM32F107 with a chip physical lan8720A.
but the Olimex board is a KS8721 PHY chip.
needs to change the code?
If so, what changes?
thank you

[JohnS]

Search web, read datasheets, etc I suppose,

I personally do not know what I should change in the program.
I changed this address const char _PHY_BSR = 1; but nothing changes.



I also tested the test program on ethernet (Olimex in the examples).
Rs232 part OK ethernet part not working. No ping the IP address.

any idea?
thank you

There are examples for both the old PHY and the new PHY available at the STM32-P107 web-page and the wiki article.

Board revision B PHY Micrel project: https://www.olimex.com/Products/ARM/ST/STM32-P107/resources/STM32-P107_DemoSoft.zip

Board revision C, PHY LAN8710A-EZC project: https://www.olimex.com/Products/ARM/ST/STM32-P107/resources/STM32_P107_revision_C_examples.zip

In that regard there are also schematics for all board revisions that are currently sold or have been previously sold.

Best regards,
