The default configuration is set up run from IRAM. However, the
|
|
|
|
|
current (2016-11-14) OpenOCD for ESP32 does not support writing to
|
2016-12-14 15:19:35 +01:00
|
|
|
FLASH. This option sets up the linker scripts to support execution
|
2016-11-15 00:51:50 +01:00
|
|
|
from IRAM. In this case, OpenOCD can be used to load directly into
|
|
|
|
|
IRAM.

|
|
|
|

|
|
|
At this stage the nuttx image is small enough to be entirely memory-
|
|
|
|
|
resident. Once board support is more mature you can add flash cache
|
|
|
|
|
mapping code to run from SPI flash after initial boot. There are at
|
|
|
|
|
least two possible approaches you could take: You can add the flash
|
|
|
|
|
cache mapping code into nuttx directly, so it is self-contained -
|
2018-07-09 02:24:45 +02:00
|
|
|
early nuttx initialization runs from IRAM and enables flash cache,
|
2016-12-14 15:19:35 +01:00
|
|
|
and then off you go. Or you can use the esp-idf software bootloader
|
|
|
|
|
and partition table scheme and have nuttx be an esp-idf "app" which
|
|
|
|
|
allows interoperability with the esp-idf system but makes you
|
|
|
|
|
reliant on the esp-idf design for these parts. Both are possible.
