Hello! I can't solve the problem. May be you have some explanation or
advice what to check?
System hangs after first byte received using ppos_input
This function invokes in UART RX interrupt:
void USART1_RxCpltCallback(void)
{
u8 v;
v = st.ppprxd;
pppos_input(st.ppp, &v, 1);
USART1_RxEnable();
}
I also tried to collect a packet and send with pppos_input_tcpip by timeout
timer interrupt. Hangs too:
// After 2ms of last byte received
void Timer5_PeriodElapsed(void)
{
u16 i;
if (0 != usartpppst.rxcnt)
{
pppos_input_tcpip(st.ppp, usartpppst.rxbuf, usartpppst.rxcnt);
}
static u32_t output_cb(ppp_pcb *pcb, u8_t *data, u32_t len, void *ctx)
{
HAL_UART_Transmit(&huart1, data, len, 0xFFFF);
return len;
}
Initialization procedure in main thread:
tcpip_init(ppp_init_done, (void*)&init);
while (! init)
vTaskDelay(1 / portTICK_RATE_MS);
st.ppp = pppapi_pppos_create(&st.netif,
output_cb, status_cb, 0);
printf("PPP=%lu\r\n", (u32)st.ppp);
pppapi_set_default(st.ppp);
ppp_set_auth(st.ppp, PPPAUTHTYPE_PAP, "pppclient", "12345678");
holdoff = 0;
pppapi_connect(st.ppp, holdoff);
vTaskDelay(100 / portTICK_RATE_MS);
USART1_RxEnable();
HAL uart interrupt preemption priority = 6
HAL systick priority = 5 (used by FreeRTOS)
configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY = 5
