|
|||
|
||||
This section is provided for Dual mode (DOUT/DIO) and Quad mode (QIO/QOUT) flash chips. Octal flash used on ESP-chips support High performance mode by default so far, you can refer to the octal flash support list below.
|
||||
|
||||
High performance mode (HPM) means that the SPI1 and flash chip works under high frequency. Usually, when the operating frequency of the flash is greater than 80 MHz, it is considered that the flash works under HPM. As far as we acknowledged, flash chips have more than two different coping strategies when flash work under HPM. For some flash chips, HPM is controlled by high performance flag (HPF) in status register and for some flash chips, HPM is controlled by dummy cycle bit.
|
||||
High performance mode (HPM) means that the SPI1 and flash chip works under high frequency. Usually, when the operating frequency of the flash is greater than 80 MHz, it is considered that the flash works under HPM.
|
||||
|
||||
For following conditions, ESP-IDF start code deals with HPM internally.
|
||||
As far as we acknowledged, there are more than three strategies for High Performance Mode (HPM) in typical SPI flash parts. For some flash chips, HPM is controlled by dummy cycle bit in the registers, while for other chips, it can be controlled by other bits (like HPM bit) in the register, or some special command. The difference in strategies requires the driver to explicitly add support for each chip.
|
||||
|
||||
.. attention::
|
||||
|
||||
It is hard to create several strategies to cover all situations, so all flash chips using HPM need to be supported explicitly. Therefore, if you try to use a flash not listed in :ref:`hpm_dc_support_list`, it might cause some error. So, when you try to use the flash chip beyond supported list, please test properly.
|
||||
|
||||
Moreover, when the `Dummy Cycle adjustment` strategy is adopted by the flash chip, the flash remains in a state in which DC is different from the default value after a software reset. The sub mode of HPM that adjusts the dummy cycle to run at higher frequency in the application is called `HPM-DC`. `HPM-DC` feature needs a feature `DC Aware` to be enabled in the bootloader. Otherwise different DC value will forbid the 2nd bootloader from being boot up after reset.
|
||||
|
||||
To enable High Performance Mode:
|
||||
|
||||
1. De-select :ref:`CONFIG_ESPTOOLPY_OCT_FLASH` and :ref:`CONFIG_ESPTOOLPY_FLASH_MODE_AUTO_DETECT`. HPM is not used for Octal flash, enabling related options may bypass HPM functions.
|
||||
|
||||
2. Enable ``CONFIG_SPI_FLASH_HPM_ENA`` option.
|
||||
|
||||
3. Switch Flash frequency to HPM ones. For example, ``CONFIG_ESPTOOLPY_FLASHFREQ_120M``.
|
||||
|
||||
4. Make sure the config option for `HPM-DC` feature (under ``CONFIG_SPI_FLASH_HPM_DC`` choices) is selected correctly according to whether the bootloader supports `DC Aware`.
|
||||
|
||||
- If bootloader supports `DC Aware`, select ``CONFIG_SPI_FLASH_HPM_DC_AUTO``. This allows the usage of flash chips that adopted `Dummy Cycle adjustment` strategy.
|
||||
|
||||
- If bootloader doesn't support `DC Aware`, select ``CONFIG_SPI_FLASH_HPM_DC_DISABLE``. It avoid consequences caused by running HPM-DC with non-DC-aware bootloaders. But please avoid using flash chips that adopts `Dummy Cycle adjustment` strategy if ``CONFIG_SPI_FLASH_HPM_DC_DISABLE`` is selected. See list of flash models that adpot DC strategy below.
|
||||
|
||||
Check whether the bootloader supports `DC Aware` in the following way:
|
||||
|
||||
- If you are starting a new project, it's suggested to enable `DC Aware` by selecting :ref:`CONFIG_BOOTLOADER_FLASH_DC_AWARE` option in the bootloader menu. Please note that, you won't be able to modify this option via OTA, because the support is in the bootloader.
|
||||
|
||||
- If you are working on an existing project and want to update `HPM-DC` config option in the app via OTA, check the sdkconfig file used to build your bootloader: (Upgrading ESP-IDF version may make this file different from the one used by bootloader to build.)
|
||||
|
||||
- For latest version (ESP-IDF v5.2 and above), if :ref:`CONFIG_BOOTLOADER_FLASH_DC_AWARE` is selected, the bootloader supports `DC Aware`.
|
||||
|
||||
- For versions in this range: (v4.4.4+, v5.0+, and v5.1+), if ``CONFIG_ESPTOOLPY_FLASHFREQ_120M`` is selected, the bootloader supports `DC Aware`. In this case, enable :ref:`CONFIG_BOOTLOADER_FLASH_DC_AWARE` to confirm this (though it will not affect bootloader in devices in the field).
|
||||
|
||||
- For versions below v4.4.4, the bootloader doesn't support `DC Aware`.
