When the chip exits deep sleep, the CPU and the flash chip are powered on
at the same time. CPU will run deep sleep stub first, and then
proceed to load code from flash. Some flash chips need sufficient
time to pass between power on and first read operation. By default,
without any extra delay, this time is approximately 900us, although
When the chip exits sleep, the CPU and the flash chip are powered on at the same time.
CPU will run rom code (deepsleep) or ram code (lightsleep) first, and then load or execute
code from flash.
Some flash chips need sufficient time to pass between power on and first read operation.
By default, without any extra delay, this time is approximately 900us, although
some flash chip types need more than that.
By default extra delay is set to 2000us. When optimizing startup time
(!!! Please adjust this value according to the Data Sheet of SPI Flash used in your project.)
In Flash Data Sheet, the parameters that define the Flash ready timing after power-up (minimum
time from Vcc(min) to CS activeare) usually named tVSL in ELECTRICAL CHARACTERISTICS chapter,
and the configuration value here should be:
ESP_SLEEP_WAIT_FLASH_READY_EXTRA_DELAY = tVSL - 900
For esp32 and esp32s3, the default extra delay is set to 2000us. When optimizing startup time
for applications which require it, this value may be reduced.
If you are seeing "flash read err, 1000" message printed to the
console after deep sleep reset, try increasing this value.
If you are seeing "flash read err, 1000" message printed to the console after deep sleep reset
on esp32, or triggered RTC_WDT/LP_WDT after lightsleep wakeup, try increasing this value.
(For esp32, the delay will be executed in both deep sleep and light sleep wake up flow.
For chips after esp32, the delay will be executed only in light sleep flow, the delay
controlled by the EFUSE_FLASH_TPUW in ROM will be executed in deepsleep wake up flow.)
