I supported the TRNG function when target is GR-LYCHEE.
GR-LYCHEE generates TRNG by acquiring the random number of Wifi module(ESP32) incorporated in it using I2C.
For supporting to CMSIS5/RTX5, I added the start-up processing of 3 toolchains (ARMCC, GCC_ARM, IAR) and the register definition of RZ/A1LU specific.
In addition, I added the linker script files to implement the dynamic HEAP the same as GR-PEACH(RZ/A1H).
This commit fixes#5840. Fix verified by running mbed_hal-lp_ticker test suite with preloaded RTC counter such that it wrapped in the middle of the suite.
Also removes explicit sleep blocking from the us_ticker implementation, since sleep blocking for us tickers is done at mbed HAL level now. This was causing one of the lp_ticker tests to fail.
deepikabhavnani did the hard work in tracking this issue down. Block
addresses are not cast to the correct type until after multiplying to
convert to byte addresses. This results in an overflow when the storage
is larger than 4 GB.
FATFilesystem declares sector count and size as uint32_t and block
device class arguments are addr and size which is uint64_t
While passing arguments to program/read/write API's of block device,
multiplication of uint32_t*uint32_t was not typecasted properly to
uint64_t which resulted in MSB truncation.
Eg. If block 0x800000 is accessed with block size 0x200, addr to be
passed (0x800000*0x200)0x100000000, but actual address passed was 0x0
which resulted in over-writting the root directory, and hence corrupted
filesystem
I modified the lack of copyright in the below header files that I added for commonizing the RZ_A1 related files.
- targets/TARGET_RENESAS/TARGET_RZ_A1XX/TARGET_RZ_A1H/mbed_drv_cfg.h
- targets/TARGET_RENESAS/TARGET_RZ_A1XX/TARGET_VK_RZ_A1H/mbed_drv_cfg.h
In the open call, the LFS_O_TRUNC flag was correctly zeroing the file, but
it wasn't actually writing the change out to disk. This went unnoticed because
in the cases where the truncate was followed by a file write, the
updated contents would be written out correctly.
Marking the file as dirty if the file isn't already truncated fixes the
problem with the least impact. Also added better test cases around
truncating files.
The current 0.1% clock tolerance is too small for certain platforms
which natural variance is larger than this. This commit increases the
tolerance to 0.5% instead.
