This is a double post with the SPRESENSE group on Facebook (-) (_) Pecory
The main sketch of rsp_sample.ino was replaced with mock_ili9341.ino, a sample sketch of the Adafruit GFX Library.
The first various patterns are drawn without any problems, but the following exceptions occur repeatedly during the last loop() process:
(Occurs after the 38th loop()
You seem to be failing to acquire some semaphore, but
·What are the exceptions?
·Are there any measures to eliminate the occurrence of exceptions?

up_assert:Assertion failed at file:semaphore/sem_post.line:118 task:init
Since you see the message, check the contents of the assert statement on line 118 of the file semaphore/sem_post.c.
Also, if you investigate the reason why Assertion did not work, you will find a clue to solving the problem.
I am in charge of SPRESENSE support for Sony.
We have investigated your inquiry.
The problem was caused by hand-on LCD libraries.
Lines 134-143 of "Adafruit_SPITFT_Macros.h" in the distributed file, write the following:
#if defined (ARDUINO_ARCH_SPRESENSE)
# undef HSPI_BEGIN_TRANSACTION
# define HSPI_BEGIN_TRANSACTION() HSPI_SET_CLOCK(); SPI_OBJECT.setBitOrder(MSBFIRST); SPI_OBJECT.setDataMode(SPI_MODE3)
# undef SPI_BEGIN
#define SPI_BEGIN() if(_sclk<0) {SPI_OBJECT.begin();HSPI_BEGIN_TRANSACTION();}
# undef SPI_BEGIN_TRANSACTION
#define SPI_BEGIN_TRANSACTION()
#endif
Add two lines as follows:
#if defined (ARDUINO_ARCH_SPRESENSE)
# undef HSPI_BEGIN_TRANSACTION
# define HSPI_BEGIN_TRANSACTION() HSPI_SET_CLOCK(); SPI_OBJECT.setBitOrder(MSBFIRST); SPI_OBJECT.setDataMode(SPI_MODE3)
# undef SPI_BEGIN
#define SPI_BEGIN() if(_sclk<0) {SPI_OBJECT.begin();HSPI_BEGIN_TRANSACTION();}
# undef SPI_BEGIN_TRANSACTION
#define SPI_BEGIN_TRANSACTION()
# undef SPI_END_TRANSACTION
#define SPI_END_TRANSACTION()
#endif
This will solve the problem.
Thank you for your report.
Thank you for your continued support for the Presense.
