Hi Team,

We’re using the MCU Boot for the RA4M2 Evaluation board from the suggested Photo –EK_RA4M2_MCUBoot_BL.

The project gets stuck at the stage- Verify the boot image and get its position.

Below is the error observed while executing the design.

Below is the storage allocation for different sectors-

Kindly, suggest a resolution for the same.

Thanks and Regards,

    Hello,

    When the RA4M2 MCU boot process stops at the “Verify boot image” stage, it indicates that the microcontroller is unable to successfully verify the integrity of the boot image being loaded.

    Here are a few possible reasons and troubleshooting steps to resolve the issue:

    • Incorrect boot image
    • Corrupted boot image
    • Memory or address configuration
    • Security settings
    • Debugging and logging
    • Consult documentation and support

    It’s important to note that the exact steps and solutions may vary depending on the specific development environment, tools, and firmware used. Therefore, consulting the relevant documentation and seeking manufacturer support is highly recommended to resolve the “Verify boot image” issue with the RA4M2 MCU.

    Thank You

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.

Thank You

    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 peRead more

    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.

    Thank You

Hello, I need to use both UART and SPI interface, FX3’s SPI interface and UART interface are shared, now my SPI is connected to FLASH, I need to power on through SPI FLASH, so I can not use its UART function, but FX3 has” 16- bit data bus UART SPI I2S” mode. In this mode, UART is mapped to GPIO46-49. Can I use the following settings to enable me to use both UART and SPI FLASH BOOT?

io_cfg.isDQ32Bit = CyFalse;

io_cfg.s0Mode = CY_U3P_SPORT_INACTIVE;
io_cfg.s1Mode = CY_U3P_SPORT_INACTIVE;
io_cfg.useUart = CyTrue;
io_cfg.useI2C = CyFalse;
io_cfg.useI2S = CyFalse;
io_cfg.useSpi = CyTure;
io_cfg.lppMode = CY_U3P_IO_MATRIX_LPP_DEFAULT;
/* No GPIOs are enabled. */
io_cfg.gpioSimpleEn[0] = 0;
io_cfg.gpioSimpleEn[1] = 0x08000000;
io_cfg.gpioComplexEn[0] = 0;
io_cfg.gpioComplexEn[1] = 0;

And, can I still use the virtual COM port function of the UART in this mode?

    Hi, You can use the" 16- bit Data Bus UART SPI I2S" configuration to use both UART and SPI. Please refer to the available GPIOs for that mode in Table 7 of the FX3 datasheet. As mentioned in the table, you must choose the proper GPIO if you want to use some GPIOs. If you want to use I2S GPIOs you haRead more

    Yes, the virtual COM port will work if you use the below configuration.

Hii,  I’m designing a dev board based on ESP32- C3 (ESP32- C3FN4) and I’m not sure if I’m good with connections for download boot.
Is it enough to put tactile switched on GPIO2 and GPIO8 towards VCC and pull down on GPIO9?

Also, should I include a connector in case the device needs to be flashed?

    Hello, You need to start your esp32 with the Low position on the Boot pin to begin the bootloader. In normal mode, u can hold a HIGH position on this pin by pullup him up with 10k, for example. Generally, you can use 2 buttons for switching modes, 1- to connect the boot pin to GND, 2- to pull the RSRead more

    Hello, You need to start your esp32 with the Low position on the Boot pin to begin the bootloader. In normal mode, u can hold a HIGH position on this pin by pullup him up with 10k, for example. Generally, you can use 2 buttons for switching modes, 1- to connect the boot pin to GND, 2- to pull the RST( EN) pin to GND- for resuming esp32 (you need to pull up it too). Also, you can use special schemes which will do it automatically.
