Re: fat32 sd-card filesystem broken

Hi Simon, I tested it recently (not extensive test) and it was working fine (stm32f777 meadow board). Did you try to run apps/testing/fstest to push its hard(ware) limits? :-) Also a simple way to verify if FAT is working is creating a RAMDISK (formatted as FAT) and run your application using

Re: Link error building c++ app with master branch

Hi Mike, Let me explain the mental process I follow to fix this kind of error! The error message in this case is very "clear" undefined reference to `pthread_key_create' So let see where it is defined: $ cd nuttxspace/nuttx $ git grep pthread_key_create ...

Re: UARTs ttyS and esp32

Please open arch/xtensa/src/esp32/esp32_serial.c and search for uart_register() function. Notice that it is wrapped by some #ifdef, that need to be satisfied to that function be called. Also if you enter inside boards/xtensa and "git grep UART1" or UART2 you will find some board configuration

Re: riscv64 libm link question

Hi Ken, Are you enabling the same symbols as in the sim bas or bastest ? $ cd nuttxspace/nuttx $ cd boards/ $ git grep "BAS=y" sim/sim/sim/configs/bas/defconfig:CONFIG_INTERPRETERS_BAS=y sim/sim/sim/configs/bastest/defconfig:CONFIG_INTERPRETERS_BAS=y $ cd .. $ ./tools/configure.sh

Re: ESP32S3 arbitrary crash when no optimization configured

Hi Mike, I remember facing similar issue with ESP32 in the past. Because I started using NuttX with ARM chip and in the past the GCC toolchain has some issue with you are trying to compile debug symbols (-g) and optimization enabled (-O2) I always disabled optimization while enabling debugging.

Re: [EXT] Re: CTU CAN FD driver multi-licence for Nuttx

I think the authors of the driver can release the source code using two or more licenses. We already have an example of it in NuttX: SocketCAN Since they add the OR license clause it is fine. BR, Alan On 9/14/23, Alin Jerpelea wrote: > Hi Pavel, > > small oftopic regarding the license

Re: make command error

Hi Miguel, It was many years ago, normally the used hello_main() etc, to avoid main() symbol collision. Now the apps can use main() and the building system will concatenate it automatically. Probably the issue that Gustavo is facing is some messing with the source code. I think he is using
