Hi,

I have upgraded the lwip from 1.3.2 to 1.4.0. In the enclosure you can find my sys_arch.c and sys_arch.h. I am not using mempools, just only malloc and free, #define MEM_LIBC_MALLOC (1) so that you will have to define other functions. The upgrading was easier than to lwip 1.3.2. All stuff around timers can be dropped with NO_SYS 0.

), one tick = 1 ms,  if you want to use is with a FreeRTOS, just only rename and  functions beginning with UEZ and redefine typedefs to xSemaphoreHandle, xQueueHandle, etc.

  Dear Martin,

  is there a way getting also your 1.3.2 sys_arch files - this will make it easy to compare the changes you've made between LwIP 1.3.2 and 1.4.0 (and which drives me a bit crazy at the moment) ;-)

  Hello Marco,

  If I remeber correctly the change was only one and it was kicking out the timers and reworked sema/queues. Thats all. In the enclosure you can find another sys_arch 1.4.0 files. A partial previous implementation (1.3.2) is between #if 0 ... #endif.

  > is there a way getting also your 1.3.2 sys_arch - No I have deleted it pernamently.

  Hi Martin,

  I am using lwip v 1.3.1 and FREERTOS as operating system. FREERTOS V 7.0.1 . I want to switch to lwip 1.4.0.I tried it but I am getting all sorts errors related to FREERTOS function declarations.

  Please can you elaborate on the last line of your post:

  "if you want to use is with a FreeRTOS, just only rename and  functions beginning with UEZ and redefine typedefs to xSemaphoreHandle, xQueueHandle, etc."

  Thanks ,

  I appreciate it.

  Hi, I would recommend to look at FreeRTOS source directory. Instead of elaborating here, I think you can find ports directly under the FreeRTOS. If not, I will describe it here.
