Just another choice for the PHY interface.
Added: Keyword option phy_clock=LAN.IN or LAN.OUT
to define the source of the 50MHZ clock for the PHY
interface. The RMII clock is not enabled if it
is generated by a PYH board. Constants:
LAN.IN The clock is provided by the PHY board.
LAN.OUT The clock is provided by the MCU board.
The default is LAN.OUT or the value set in mpconfigboard.h, which
is currently set to IN only for the SEEED ARCH MIX board. Usage etc:
lan = LAN(phy_type=LAN.PHY_DP83848, phy_clock=LAN.IN)
The initial problem with a wrong ICMP checksum was caused by
the test code setting a checksum and the HW taking that probably as
the start value and ending up with 0xffff. With a checksum field of 0
set by the test code the HW creates the proper checksum.
Useful for boards without a PHY interface, where that has to be
attached. Like the Seed ARCH MIX board or Vision SOM. Phy drivers
supported so far are:
- KSZ8081
- DP83825
- LAN8720
More to come. Usage e.g.:
lan = LAN(phy_type=LAN.PHY_LAN8720, phy_addr=1)
The default values are those set in mpconfigboard.h.
UART 0 is attached to the Debug USB port. The settings are
115200 Baud, 8N1.
For MIMXRT1010_EVK this is identical to UART1. For the other boards,
this is an additional UART.
The pico-sdk 1.3.0 update in 97a7cc243b
introduced a change that broke RP2 Bluetooth UART, and possibly UART in
general, which stops working right after UART is initialized. The commit
raspberrypi/pico-sdk@2622e9b enables the UART receive timeout (RTIM) IRQ,
which is asserted when the receive FIFO is not empty, and no more
characters are received for a period of time.
This commit makes sure the RTIM IRQ is handled and cleared in
uart_service_interrupt.
The current ST HAL does not support reading the extended CSD so cannot
correctly detect the capacity of high-capacity cards. As a workaround, the
capacity can be forced via the MICROPY_HW_MMCARD_LOG_BLOCK_NBR config
option.
