how to connect to XMC4800 board after make install

Follow the installation of XMC. got the gdb connected to the XMC4800.
how do i test the micropython on this board
trying picocom with variuos baudrate to /dev/ttyAMA0 port but never get a response from the board.

MicroPython as a Package for Unix

Hi,
To understand the micropython building procedure, I choose "/unix" and I built it successfully and bin file got generated. Now, I want to ad as a package instead of binary image. So suggest a procedure to install as a package in Linux PC.

Incorrect C_SIZE_MULT in sdcard driver

The count() method returns the wrong number of sectors in this port.

This is because the wrong SIZE_MULT calculation constant is used in the init_card() function

https://github.com/micropython/micropython-infineon/blob/master/drivers/sdcard/sdcard.py#L81

self.sectors = ((csd[8] << 8 | csd[9]) + 1) * 2014

The V2 CSD structure returns the card size in 512KB chunks.

The normal calculation as per the sdcard.org specification (SD Specifications, Part 1, Physical Layer Simplified Specification Version 2.00 September 25, 2006) is:

nbytes = ((CSIZE-1) * 512 * 1024)  # V2 cards always report in 512KB chunks
nblocks = nbytes / 512  # V2 cards always work with a 512 byte sector/BLOCK_LEN

This reduces to:

nblocks = (CSIZE-1) * 512 * 1024 / 512
nblocks = (CSIZE-1) * 1024

I guess this is just a typo by the original author, as you have the same digits but transposed.

Question about values returned by time() function? Seem to be 20 years late?

Typical result (for recent date) on an ESP8266 would be 605078638 using the ntptime module in MicroPython. Which obviously converts to a human readable date/time format, such as Sun, 05 Mar 1989 05:23:58 +0000 but clearly the month and day are correct but the year is off by 20 years? Should be closer to something like 1551764000, no? Packet is sent to NTP source and received as expected just not the result expected.

THIS PROJECT REPO IS NO LONGER ACTIVE

Please instead go to:
