Realtek RTL8195AM prints out extra messages on serial port

[SeppoTakalo]

Description

When running Mbed OS network tests+socket test RTL8195AM sometimes prints out extra messages into the serial port which may break the test result parsing.

For example, following message occasionally appear

[_rtx2_create_task] [rtw_little_wifi_mcu_thread]priority is higher than osPriorityRealtime

Also, following message appears on every boot:

gcc version 4.8.3 (Realtek ASDK-4.8.3p1 Build 2003)

Check boot type form eFuse

SPI Initial

Image1 length: 0x4398, Image Addr: 0x10000bc8

Image1 Validate OK, Going jump to Image1

SDR Controller Init

These extra messages have possibility to break Mbed OS testing that depends on correct serial port output.

This does not fix it: #9202 ?

Looking at the report and the PR, it only addressed Wifi interface , the above seems to be also in other parts.

Hmm..

It might have hidden all, but not boot messages.

Also the first example probably comes from RTX debug functions.

Hi @SeppoTakalo ,
Thank you for helping us discover this bug, I am debugging it now.

Hi @SeppoTakalo，

The [_rtx2_create_task] [rtw_little_wifi_mcu_thread]priority is higher than osPriorityRealtime warning message has been concealed.

However, as the following messages are burned in the ROM, they cannot be concealed.

Check boot type form eFuse
SPI Initial
Image1 length: 0x4398, Image Addr: 0x10000bc8
Image1 Validate OK, Going jump to Image1
SDR Controller Init 

Other than these, have you noticed any other redundant messages so far, so that I can solve them together with one commit?

Many thanks.

This is the only one that I can find anymore (other that those already mentioned)

[timer_wrapper] Fail to find the timer_entry in timer tablefailed: -1

Also this, but actually not related to this, because it seems to be Daplink failure:

<RTL8195A>
================================<DAPLink:Overflow>
4.8.3 (Realtek ASDK-4.8.3p1 Build 2003)

So if you can still check the timer_wrapper then I think this can be closed once you submit fixes.

Hi @AdamZhang0124 , have you got the chance to check the timer_wrapper as Seppo suggested?

[AdamZhang0124]

Hi @samchuarm , the timer_wrapper message seems to be a real error message rather than a debugging message. I have not encountered it before. As I checked, it is related to wlan, and if this message occurs, this error may cause the mismatch of the timer values.

Hi @SeppoTakalo , could you please help to double check if this error message still exists and whether this error would cause other problems?

Many thanks!

[samchuarm]

Hi @SeppoTakalo , would you be able to help check if you can still see the timer_wrapper error message? Thanks.

Hi @SeppoTakalo , can you please help check if this is still an issue or it can be closed? Thanks.
