Interrups were blocked 1*n/baud Seconds. The former comment indicates
there was an asumption that the TXE would be set at DMA completion.
In reality this is not true. There can be 1 char in the TX Shift
register and one in the TX holding register, when DMA completes.
Waiting on TXE is not needed at all. The DMA will resume on the
DMA req when the TX holding register is written to the TX Shift
register.
so size with nuttx could report the correct bss value:

malloc() and free() should never be used within the OS. This will work in the FLAT build because there is only a single heap, but will cause problems in PROTECTED and KERNEL build modes where there are separate heaps for user and kernel memory.
Typically kmm_malloc(), kmm_zalloc(), and kmm_free() should be called within the kernel in those build modes to use the kernel heap.
Memory is never free. Possible memory leak:
./boards/arm/cxd56xx/common/src/cxd56_crashdump.c: pdump = malloc(sizeof(fullcontext_t));
Memory allocated with malloc(), but freed with kmm_free():
./drivers/usbhost/usbhost_composite.c: cfgbuffer = (FAR uint8_t *)malloc(CUSTOM_CONFIG_BUFSIZE);
Memory is never freed in these cases. It is allocated in the driver initialization logic, but there is no corresponding uninitialization logic; memory is not freed on error conditions:
./arch/arm/src/lc823450/lc823450_i2s.c: priv = (struct lc823450_i2s_s *)zalloc(sizeof(struct lc823450_i2s_s));
./arch/arm/src/sam34/sam_spi.c: spics = (struct sam_spics_s *)zalloc(sizeof(struct sam_spics_s));
./arch/arm/src/sama5/sam_spi.c: spics = (struct sam_spics_s *)zalloc(sizeof(struct sam_spics_s));
./arch/arm/src/samv7/sam_spi.c: spics = (struct sam_spics_s *)zalloc(sizeof(struct sam_spics_s));
Memory is allocated with zalloc() but freed on error conditions with kmm_free():
./arch/arm/src/sama5/sam_ssc.c: priv = (struct sam_ssc_s *)zalloc(sizeof(struct sam_ssc_s));
./arch/arm/src/samv7/sam_ssc.c: priv = (struct sam_ssc_s *)zalloc(sizeof(struct sam_ssc_s));
./arch/arm/src/stm32/stm32_i2s.c: priv = (struct stm32_i2s_s *)zalloc(sizeof(struct stm32_i2s_s));
Memory is never freed:
./drivers/spi/spi_bitbang.c: priv = (FAR struct spi_bitbang_s *)zalloc(sizeof(struct spi_bitbang_s));
arch/arm/src/cxd56xx/cxd56_gnss.c, arch/arm/src/xmc4/xmc4_spi.c,
crypto/blake2s.c, drivers/lcd/pcf8574_lcd_backpack.c, drivers/lcd/st7032.c
User space memory should not be used within the OS and, when it is absolutely necessary to use user-space memory, it should be allocated using kumm_malloc().
clang-check complained like the following.
While this is not a real bug, it's easy to appease.
sim/up_exit.c:68:21: warning: Value stored to 'tcb' during its initialization is never read
FAR struct tcb_s *tcb = this_task();

ESP32 runs code in a SPI Flash, so users can also use it to store
data directly or mount some parts into a filesystem.
The SPI Flash usually use SPI0.
