[SOLVED] using another buffer in the control block.

i'm debugging an nrf52840 board using j-link, i wanted to add another channel to log my specific data to separate it from the rest of the logs.
i tried to define a buffer in my main.c file (512 bytes) and call

uint8_t index = SEGGER_RTT_AllocUpBuffer("TERM_2", my_buffer, sizeof(my_buffer), SEGGER_RTT_MODE_BLOCK_IF_FIFO_FULL);

the index i get is 1 which is obvious, also i verified that MaxNumUpBuffers is indeed 2.
after that i try to log using

SEGGER_RTT_WriteString(1, "\ntesting channel 1\n");

i get nothing, if i log to channel 0 i do get those strings so it's working and jlink identified the CB signature. so what am i missing ?

right of course
i'm using JLinkRTTViewer. opening another channel window (i get 0 by default and opening the second one). in the all tab and 0 tab i do see messages that are sent to SEGGER_RTT_WriteString(0,....) but if i do the same for 1 i don't see it in the viewer.

according to the manual indeed you are right. thanks for that.

Eyal.
