From 40f5ecd3a82e810203b39131cb61474f101de58e Mon Sep 17 00:00:00 2001 From: Paul Sokolovsky Date: Tue, 12 Apr 2016 00:37:04 +0300 Subject: esp8266: Add Python modules for initial configuration. Main entry point is _boot.py which checks whether FAT FS in flash mountable, and if so, mounts it. Otherwise, it checks if flash is empty, and if so, performs initial module setup: makes FAT FS, configures default AP name, etc. As a last option, if flash is not empty, and could not be mounted, it means filesystem corruption, and warning message with instructions is printed in an infinite loop. --- esp8266/scripts/flashbdev.py | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+) create mode 100644 esp8266/scripts/flashbdev.py (limited to 'esp8266/scripts/flashbdev.py') diff --git a/esp8266/scripts/flashbdev.py b/esp8266/scripts/flashbdev.py new file mode 100644 index 000000000..1d120b920 --- /dev/null +++ b/esp8266/scripts/flashbdev.py @@ -0,0 +1,29 @@ +import esp + +class FlashBdev: + + SEC_SIZE = 4096 + START_SEC = 0xa0000 // SEC_SIZE + NUM_BLK = 64 + + def __init__(self, blocks=NUM_BLK): + self.blocks = blocks + + def readblocks(self, n, buf): + print("readblocks(%s, %x(%d))" % (n, id(buf), len(buf))) + esp.flash_read((n + self.START_SEC) * self.SEC_SIZE, buf) + + def writeblocks(self, n, buf): + print("writeblocks(%s, %x(%d))" % (n, id(buf), len(buf))) + assert len(buf) <= self.SEC_SIZE, len(buf) + esp.flash_erase(n + self.START_SEC) + esp.flash_write((n + self.START_SEC) * self.SEC_SIZE, buf) + + def ioctl(self, op, arg): + print("ioctl(%d, %r)" % (op, arg)) + if op == 4: # BP_IOCTL_SEC_COUNT + return self.blocks + if op == 5: # BP_IOCTL_SEC_SIZE + return self.SEC_SIZE + +bdev = FlashBdev() -- cgit v1.2.3
