The Pyboard 1.1 has 1 MByte flash, with ~95k for the internal file system. But it has a built-in SD card socket. Since the STM32 port is not based on a RTOS, it is generally smaller. The Pyboard D's have more flash, but require lower supply voltages. Generally it could be easier to consider using a ...

Reboot as the big hammer should work.

You can try accessing as sudo, or you have to add yourself as user to the dialout group.
There might also be another process still using the device.

There are a few completely unrelated topics here. - the .fls and .bin file have effectively the same content, but are just differently coded. - The machine_uart.c code does not have any effect on firmware size or size of the user space, besides the obvious, in that changing the code may increase or ...

I have updated my W600 branch to include wm_uart.c and wm_uart.h, which will give you uart.any() and 300 baud support. If at any time the WM_SDK is changed accordingly, these files can be omitted again. Since there is no public repository for the SDK, I cannot make PRs for that.

I have a copy of the WM_SDK in my github repository which includes the avail function. At later changes I added the respective modules form the WM-SDk to the W60x source tree. Like for the SPI and watchdog/ticks+delay functions. I could do so with the UART module, If you take machine_uart.c from the...

Your question is not clear. Are you talking about RAM of flash?
If flash, are you talking about the size of the firmware, which is static, or the free space in the file system, which varies with the files stored in it.

I did a similar thing. The flash space (384k) that is used then was intended for loading packed images (the xxx.bin.gz file) by the loader. So as long as you keep loading .fls files, this space is not used and can safely be used by the firmware.

You have to terminate all other programs which use that port. Eventually you have to restart you PC. And you could try to run that esptool.py command with sudo.

you can always use esptool.py to erase the flash.

esptool.py -p <port name> erase_flash
