Hi, I need to read SPI registers from the assignment as well as ISR. So setting a flag isn’t an option and I can’t take semaphores from ISR. Is there a way to block the R_SPI_WriteRead function? Thank You Alex Thomas

Hi @Alex did you upload the STEVAL- MKI109V3 the latest firmware version? However, you can discover it in the FIRMWARE ProfiMEMSTool board folder, If not. It should be version v.3.48.3. Thank You Julian White

Hello.
Is there a way to enter bootloader/ download mode by calling a certain function in the user app?
For example, I am aware of a function
CODE SELECT ALL esp_restart()
that will only reset the CPU and it’ll boot back to the user app.
But what I want is another function or a number of codes that resets the CPU and makes it so that it wouldn’t jump to the user app and rather would stay in the bootloader.
I searched, but could not discover any information on that. I tried configuring GPIO9 strapping pin as an output, writing 0 to it, and calling the esp_restart() function, but that did not work, probably because strapping pins aren’t sampled after the software reset.
Thank You

Note that this register is typically intended for DWC- OTG use, and as the C3 doesn't have this, I am not sure if we tested the functionality there, but you can try the following CODE SELECT ALL (RTC_CNTL_OPTION1_REG,RTC_CNTL_FORCE_DOWNLOAD_BOOT); esp_restart(); Thank You JuliRead more

Hey, I am creating a smash barrier controller with ESP32 SX1276 LoRa microcontroller, and I require a 5V external power force, but I can not find anywhere which pin of 5V is the VIN one, I do not want to ruin my module, so does anyone know this particular module and which of the 5V pins is the VIN one? I have uploaded the board setup for reference purposes. If you want any extra information please let me know.

Hello, They are likely both connected to the Vin signal; check with a multimeter if there is continuance between the two pins if you want to make sure. Thank You Nidhi Singh

Hello,
I am designing a PCB that’s using the built-in serial/JTAG controller and OTG peripheral of the ESP32-S3. It can not hold a physical boot or reset buttons. It has a USB-C container with the D/D- lines connected to GPIO20 and GPIO19, respectively.
Are there any ways of going without buttons for reset or is an external USB to UART IC needed?
For boot mode choosing I exactly hold a jumper that when shorted pulls GPIO0 to GND, is there a better way to do that without a button?
Any help is appreciated.

Hello, The USB-serial-JTAG port can usually reset/put the chip into boot mode without any external components.

It’s still advised to have some way to pull IO0 low for initial programming and during development, if you make a mistake where e.g. your program disables the USB function. A jumper will perform that function just fine.

Hello, I am planning to use RA2A1 MCU for a design with 24-bit ADC sampling and relay control.
Because there are many 5V peripherals in this system, it’ll be much simple if the RA2A1 runs at a 5 Volt power supply.
Most of the RA2A1 examples are running at a 3.3 V power supply, what’s the potential problem if run at a 5 V power supply?

Hello, None RA2 family can run from 1.6 V to 5V. The data sheet & hardware user manual that can be found on the Renesas web give further detail. Thank You

Hi Alex,
The exchange mode for MCU boot uses the scratch area as an intermediate area in order to complete the exchange of the 2 images. The process of switching is done like below. However, then no information is lost, If a power failure occurs.
The scratch area must be large enough to store the largest sector that’s going to be shifted. For RA2 MCUs, the scratch area should be set up to 0x800 when exchange mode is used.

Hii,
In TLE9471ES when VCAN_UV is touched off the TLE9471ES will disable the CAN transmitter.
That means the CAN event is still in working condition.
So, my question is when the VCAN_UV fault is still present can the CAN signals be dependable to read use for further action?

Hii,
Thanks for your query.
The voltage at the CAN supply pin is covered in CAN Normal and Receive Only Mode. In the case of VCAN
Undervoltage signalization via SPI bit VCAN_UV is touched off and the TLE9471ES disables the transmitter stage.
If the CAN supply reaches a higher position than the under-voltage finding threshold (VCAN>VCAN_UV,r), the transceiver is automatically switched back to CAN Normal Mode.
The under-voltage finding is enabled if the mode bit CAN_1 = ‘ 1 ’, i.e., in CAN Normal or CAN Receive Only
Mode. As the Receiver is also powered by the VCAN, in case of insufficient supply, it may not transmit the signals correctly and admit them correctly. PFA for further information.

Hello,
We are changing a product from a Community to an RA processor. Can we use the same E2 Studio and switch between SSP and FSP? We’ll have times when we are doing maintenance on the Community product and also doing dev on the new RA board.
Is there a specific version of E2 that can do this?
Does it make sense, or should we’ve two different E2 setups?
Thanks

Hi Alex,
The FSP and SSP releases are at a different meter and each version released is tested/ qualified against a specific version of e2-studio. The distribution download of the platform installer will ensure that the proper version of e2-studio will be with the FSP/ SSP version.

Hello Alex,
By default, the perpetration of the drivers in FSP is nonblocking. This is happening to improve the effectiveness of your code. That is the reason callback functions are added in order to be sure that the operation you want to perform is completed.
Let’s say for example that you want to perform a UART read, and you call R_SCI_UART_Read() API, this API’ll return immediately and your code will enter the callback function you created in order to check if data is ready and if the read operation is actually completed.
In case you would like to make blocking the operation of R_SPI_WriteRead() maybe you should consider adding a wait after the call of the API in your code by using R_BSP_SoftwareDelay(), if this is what you’re meaning.
By making tests you can find the proper delay you need to set.
Thank you!
