Hello,

I have a TMP117 sensor EK- RA6M5 test setup on my desk, but the IIC0 bus channel doesn’t work for me when I use Pin group B (407 SDA, 408 SCL), but when I switch to Pin group A (401 SDA, 400 SCL), it works OK.

I need it to work with Pin Group B because pins 401 and 400 are used for another purpose on my board.

Please see attached screenshots of my setup.

Thank you in advance!

    Hello, The P407 pin in the EK-RA6M5 board is applied as the USB VBUS control pin according to the schematics diagram As you can know there are pull-down resistors R26 and capacitor C59 which probably cause malfunctioning of the I2C interface. However, you can test to apply the different channels ofRead more

    Hello,

    The P407 pin in the EK-RA6M5 board is applied as the USB VBUS control pin according to the schematics diagram

    As you can know there are pull-down resistors R26 and capacitor C59 which probably cause malfunctioning of the I2C interface.

    However, you can test to apply the different channels of the IIC machine or the SCI module in the I2C mode, If pins P400 and P401 are already in use.

    Kind regards,

    Alex

Hello,

I’m trying to import, make and flash some of the example projects included in the archive”ek_ra6m5-exampleprojects.zip”

Still, for a good number of these, it seems they’ve not been updated or maintained to keep up with changes in the FSP leading to numerous errors and warnings in the Stacks configuration tab on importing the design, numerous of which are flagging up deprecated settings and/ or settings that are needed to be set but aren’t set.

    Hi, As the clock speed is allowed by FSP configuration, it should be safe for all the peripherals. For example, I've tested OSPI with a clock source from MOCO and set it at 8 MHz. Could you share what makes you suppose it isn't working correctly? Regards,

Whent theR_ETHER_Write is called andp_reg_edmac-> EDTRR = ETHER_EDMAC_EDTRR_TRANSMIT_REQUEST; edmac started a malformed packet is send see wireshark trace under.

“Set trust zone boundaries” parameter is” yes” in debugger configuration.
Can you help me.

Also, there is a question in Wireshark about Malformed Packet BOOTP/ DHCP too, and the issue disappeared when he updated to a newer version of Wireshark. It might help.

On page 89 of the Renesas RA6M5 specification, there is a sentence “The use of pins AN000 to AN010, AN012, AN013 as digital outputs is not allowed when the 12-Bit A/D converter is used.” If pins AN000 to AN010, AN012, AN013 ...Read more

If pins AN000 to AN010, AN012, AN013 are used as digital outputs when using ADC, what will be the impact and result?

    As this is not allowed, the result is not specified in the data sheet. If the pins were used as inputs while the ADC is being used (with an Analog signal on the inputs), you would have the output of the device fighting with the input.

    If the pins were used as inputs while the ADC is being used (with an Analog signal on the inputs), you would have the output of the device fighting with the input. This could cause many issues- from excess noise to possible over heating and even potential wear/damage to the device pins.
