    No, If you want to use Arduino for development, the only way to use such functionality is to use Arduino as IDF component.

    “SW_CPU_RESET” is the software reset log. For example, calling the “esp_restart()” API will print this log.

We will use a ESP32-C3FH4 in a project. We will not have a external flash. Is it possible to use all GPIO’s including the ones dedicated to flash SPI as plane I/O’s?

The DA7212 supports 2 Digital mics on MIC1 channel and can support one Analog mic on the MIC2 channel.

The datasheet says that the ADC digital filter is shared for the analog/digital mic channels. So either the analog mic or digital mic can use this ADC digital filter

Can I get the Analog Mic ADC data to the I2S without using the ADC digital filter.  If this is possible, then can I add 2 digital microphones on the MIC1 channel( I can do the digital filtering on the Analog mic in my firmware )?

    You can use the AMIC and DMIC, however both will effectively go through the ADC filters. If you enable the ADC_FILTER1, which has the voice and music filters both paths (AMIC, DMIC), will be effected by the filters.

I am seeing a strange behaviour on my custom board (R7FA6M3AH + FSP 3.3) since I configured my application to build as a MCU boot image. The application works correctly in standalone but when booted from MCU boot, network was not working and by investigating I found that the interrupt (EDMAC0_EINT) gets called but executes the Reset_Handler which causes an assert later on in FreeRTOS (vportEnterCritical gets called from an ISR).I have other devices interrupts working fine for the same binary (such as an uart over RCI) and got simpler applications to work with the network on top of MCU boot so I don’t believe it is solely due to MCU boot but after a couple of days of debugging I’m really short on ideas on what could cause the problem.

    It was caused by too many interrupts declared with a non-aligned vector table. The ARM NVIC requires that the vector table must be offset to an address aligned on 4*N where N is the number of interrupts rounded to the upper power of 2.

    It was caused by too many interrupts declared with a non-aligned vector table. The ARM NVIC requires that the vector table must be offset to an address aligned on 4*N where N is the number of interrupts rounded to the upper power of 2. In my case I have 17 interrupts which gives 17 + 16 (standard exceptions) = 33 -> 64. Therefore I needed to align on 256 = 0x100. To fix the alignment I changed the header size in MCUBoot bootloader project to 0x100 instead of the default 0x80. Note that the signing command needs to be updated as well as it includes the header size in the options.

    Hi Linto,

    Before starting the work on RA Family MCU, you need to download the software of e2 studio IDE and FSP (Flexible software package) from Renesas website.

    After installation the software you need to go new stack and select the peripherals what you require then generate the code.

    Please follow the below link instruction for getting stating.
