6cefbc0c3f This change provides an option to add /dev/urandom to all architectures. The pseudo-random algorithm I choose strikes an arguably-good balance between being "random" and small/fast enough for 8/16 bit MCUs. It’s the well-documented xorshift128 algorithm. It has an internal state of 128 bits that can be [re-]seeded with a write. 2016-07-17 06:42:26 -06:00

74037a7951 Merged in ziggurat29/nuttx/stm32l4_smartfs_test (pull request #97)
fixes to n25qxxx mtd driver for smartfs support, etc...

74777499bc alter the notion of 'blocksize' to be equivalent to 'flash write page size' in order to align with assumptions in the smartfs driver (at least, maybe other things do as well).
Correct a bug that was previously masked by having blocksize=eraseblocksize which would cause buffer overflows and delicious hardfaults.
Trivial spelling changes in comments, etc.

0d41a1cd42 Before accessing the sst26 flash, the "Global Unlock" command must me executed, which I do in the sst26 driver.
BUT. re-reading the datasheet, the WREN instruction is required to enable the execution of this command. This was not done.

I have no idea how the driver currently works except by chance. The writes
should never happen at all, the flash is half-enabled!

2cadf783fd cdcacm_unbind leaks write request objects. This arises due to freeing the
bulk IN endpoint before the loop that frees the requests via cdcasm_freereq.
That function checks the parameters and skips the freeing if either is NULL.
Freeing the bulk IN enpoint will cause the first param to be NULL, thereby
bypassing the free operation.  To fix, I moved the release of the bulk IN
endpoint until after to loop (much as was the case for the OUT and read
requests, which did not exhibit the problem).

3d5e690977 Shadow-Mode: The output- and configuration registers of the IO-Expander
are held in the microcontrollers memory and only written to the IO-Expander.
 This reduces bus traffic and is more error-proof than the normal read-
 modify-write operation.

 Retry Mode: If enabled and an error occurs while writing to the IO-Expander the
 current transmission is automatically repeated once.
