When ESP32 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
|
|
some flash chip types need more than that.
|
|
|
|
By 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.
