4 Boot Configurations

Note: The content below is excerpted fromESP32-C5 Series Datasheet> SectionBoot Configurations. For the strapping pin mapping between the chip and modules, please refer to Chapter8Module Schematics. The chip allows for configuring the following boot parameters through strapping pins and eFuse parameters at power-up or a hardware reset, without microcontroller interaction.

• Chip boot mode – Strapping pin: GPIO26, GPIO27, and GPIO28
• SDIO sampling and driving clock edge – Strapping pin: GPIO25 and MTDI
• ROM message printing – Strapping pin: GPIO27 – eFuse parameter: EFUSE_UART_PRINT_CONTROL and EFUSE_DIS_USB_SERIAL_JTAG_ROM_PRINT
• JTAG signal source – Strapping pin: GPIO7 – eFuse parameter: EFUSE_DIS_PAD_JTAG, EFUSE_DIS_USB_JTAG, and EFUSE_JTAG_SEL_ENABLE
• Crystal frequency selection – Strapping pin: MTMS (effective only in Joint Download Boot mode) – eFuse parameter: EFUSE_XTAL_48M_SEL and EFUSE_XTAL_48M_SEL_MODE The default values of all the above eFuse parameters are 0, which means that they are not burnt. Given that eFuse is one-time programmable, once programmed to 1, it can never be reverted to 0. For how to program eFuse parameters, please refer toESP32-C5 Technical Reference Manual> ChaptereFuse Controller. The default values of the strapping pins, namely the logic levels, are determined by pins’ internal weak pull-up/pull-down resistors at reset if the pins are not connected to any circuit, or connected to an external high-impedance circuit. Table 5: Default Configuration of Strapping Pins Strapping Pin Default Configuration Bit Value GPIO25 Floating – GPIO26 Floating – GPIO27 Pull-up 1 GPIO28 Pull-up 1 GPIO7 Floating – MTMS Floating – MTDI Floating – Espressif Systems 15 Submit Documentation Feedback ESP32-C5-WROOM-1 & WROOM-1U Datasheet v0.5

To change the bit values, the strapping pins should be connected to external pull-down/pull-up resistances. All strapping pins have latches. At Chip Reset, the latches sample the bit values of their respective strapping pins and store them until the chip is powered down or shut down. The states of latches cannot be changed in any other way. It makes the strapping pin values available during the entire chip operation, and the pins are freed up to be used as regular IO pins after reset. For details on Chip Reset, see ESP32-C5 Technical Reference Manual> ChapterReset and Clock. The timing of signals connected to the strapping pins should adhere to thesetup timeandhold time specifications in Table6and Figure5. Table 6: Description of Timing Parameters for the Strapping Pins Parameter Description Min (ms) tSU Setup timeisthetimereservedforthepowerrailstostabilizebe- fore the CHIP_PU pin is pulled high to activate the chip. 0 tH Hold timeis the time reserved for the chip to read the strapping pin values after CHIP_PU is already high and before these pins start operating as regular IO pins.

load methods:

• UART Download Boot
• SDIO Download Boot In SPI Boot mode, the ROM bootloader loads and executes the program from SPI flash to boot the system. In Joint Download Boot 0 mode, users can download binary files into flash using UART0, USB, or SPI Slave interfaces. It is also possible to download binary files into SRAM and execute it from SRAM. InJointDownloadBoot1mode, userscandownloadbinaryfilesintoflashusingUART0orSDIOinterfaces. Itis also possible to download binary files into SRAM and execute it from SRAM.

4.2 SDIO Sampling and Driving Clock Edge Control

The strapping pin GPIO25 and MTDI can be used to decide on which clock edge to sample signals and drive output lines. See Table8SDIO Input Sampling Edge/Output Driving Edge Control. Table 8: SDIO Input Sampling Edge/Output Driving Edge Control Edge behavior GPIO25 MTDI Falling edge sampling, falling edge output 0 0 Falling edge sampling, rising edge output 0 1 Rising edge sampling, falling edge output 1 0 Rising edge sampling, rising edge output 1 1

1 GPIO25 and MTDI are floating by default, so above are not

default configurations.

4.3 ROM Messages Printing Control

During the boot process, the messages by the ROM code can be printed to:

• (Default) UART0 and USB Serial/JTAG controller
• UART0 Espressif Systems 17 Submit Documentation Feedback ESP32-C5-WROOM-1 & WROOM-1U Datasheet v0.5

• USB Serial/JTAG controller To print ROM messages toUART0 orUSB Serial/JTAG controller, see the description below. EFUSE_UART_PRINT_CONTROL and GPIO27 control printing ROM messages toUART0 as shown in Table9 UART0 ROM Message Printing Control. Table 9: UART0 ROM Message Printing Control UART0 ROM Message Printing Register2 eFuse3 GPIO27 ROM messages are always printed to UART0 during boot 0 (0b00) x4 Print is enabled during boot 1 (0b01) 0 Print is disabled during boot 1 Print is disabled during boot 2 (0b10) 0 Print is enabled during boot 1 Print is disabled during boot 3 (0b11) x Print is disabled during boot 1 x x 1 Bold marks the default value and configuration.

Table 10: USB Serial/JTAG ROM Message Printing Control USB Serial/JTAG ROM Message Printing EFUSE_DIS_USB_SERIAL_JTAG_ROM_PRINT Enabled 0 Disabled 1 Ignored 1 Bold marks the default value and configuration.

4.4 JTAG Signal Source Control

The strapping pin GPIO7 can be used to control the source of JTAG signals during the early boot process. This pin does not have any internal pull resistors and the strapping value must be controlled by the external circuit that cannot be in a high impedance state. As Table11shows, GPIO7 is used in combination with EFUSE_DIS_PAD_JTAG, EFUSE_DIS_USB_JTAG, and EFUSE_JTAG_SEL_ENABLE.

6 In Joint Download Boot 1 mode, the USB Serial/JTAG controller is forcibly disabled, and

the JTAG signal only comes from JTAG pins. If PAD_JTAG is also disabled, then JTAG is disabled.

4.5 Crystal Frequency Selection

ESP32-C5 supports crystal frequencies of 40 MHz and 48 MHz.Boot modestogether with MTMS, EFUSE_XTAL_48M_SEL, and EFUSE_XTAL_48M_SEL_MODE collectively control the crystal frequency. Table 12: Crystal Frequency Selection Crystal Frequency Boot Mode eFuse 12 eFuse 23 MTMS

5.2.1.12 BitScrambler

The ESP32-C5 has an extensive amount of DMA-capable peripherals. These can move data from memory to an external device, and vice versa, without any interference from the CPU. This only works if the external device needs or emits the data in question in the same format as the software expects it: if not, the CPU needs to rewrite the format of the data. Examples include a need to swap bytes, reverse bytes, and shift the data left or right. As bitwise operations tend to be fairly CPU-expensive and the purpose of DMA is to not use the CPU in the transfer, ESP32-C5 integrates one BitScrambler, which are dedicated peripherals to change the format of data in between memory and the peripheral. The RX channel is dedicated to peripheral-to-memory transfers, and the TX channel is dedicated to memory-to-peripheral transfers. The BitScrambler is capable of performing the Espressif Systems 27 Submit Documentation Feedback ESP32-C5-WROOM-1 & WROOM-1U Datasheet v0.5

• If an external antenna ANT2 is used, it is recommended to reserve an RF circuit as shown in the figure above. By default, ESP32-C5-WROOM-1U uses ANT1, and ANT2 is disabled. To use ANT2, please contactus.
• Please control the voltage levels of strapping pins. For more details, please refer to Chapter4Boot Configurations.
• Soldering the EPAD to the ground of the base board is not a must, however, it can optimize thermal performance. If you choose to solder it, please apply the correct amount of soldering paste. Too much solderingpastemayincreasethegapbetweenthemoduleandthebaseboard. Asaresult,theadhesion between other pins and the baseboard may be poor.
• To ensure that the power supply to the ESP32-C5 chip is stable during power-up, it is advised to add an RC delay circuit at the EN pin. The recommended setting for the RC delay circuit is usually R = 10 kΩ and C = 1µF. However, specific parameters should be adjusted based on the power-up timing of the module and the power-upand resetsequencetiming of the chip. For ESP32-C5’spower-upand resetsequence timing diagram, please refer toESP32-C5 Series Datasheet> SectionPower Supply.
