Ticket Name: PROCESSOR-SDK-TDAX: "AR12XX: FAULT: BSS CPU fault!!" seen frequently, forcing user to reboot radar

Query Text:
Part Number: PROCESSOR-SDK-TDAX Other Parts Discussed in Thread: MMWCAS-DSP-EVM, MMWCAS-RF-EVM, AWR2243, AWR1243, TDA2 Hello, I have an MMWCAS-RF-EVM mounted on MMWCAS-DSP-EVM. I'm using PROCESSOR_SDK_RADAR_ 3.08 and often times I'm seeing this error on my terminal window. [IPU1-0] 1300.877569 s: radar_ar12xx/src/bspdrv_ar12xxPriv.c @ Line 541: [IPU1-0] 1300.877691 s: AR12XX: FAULT: BSS CPU fault!!

The hardware version reported by the serial terminal is ES3.0. I don't seem to have this problem happen this frequently in the ES1.0 hardware that I have. Please tell me how to isolate and fix this problem? Is there a firmware update I'm missing? Thanks Asher

Responses:
Hi, ES1.0 and ES2.0 have different version of radar firmware. During radar init, it should try to check the revision of radar and download the corresponding firmware. You can check the log to see if the ES version of radar was detected correctly. Regards, Stanley

Hi Stanley, We have 2 Cascade RF boards where both boards have AWR2243 transceivers. However one board has hwMajor of 1 and the other has hwMajor 3. We believe these numbers represent ES1.0 and ES3.0. Since we have 2 AWR FW binary files for AWR1243 and AWR2243, Both cascade boards are downloaded with 2243 FW disregards whether one is an ES1.0 and the other is an ES3.0. That's how we modified the TDA2 bootup code to detect and behave. Please tell us if that assumption is correct. Now back to the BSS and ESM Faults above, we've seen this error showed up very often on the ES3.0 HW version vs the ES1.0 HW version even though both are running with same 2243 FW. So we are wondering if ES3.0 HW version has an updated FW for it to be used that fixes above errors seen? Thank you, --Khai

Hi Khai, I have forwarded this question to our Radar team to comment. In Radar SDK, only AWR1243 ES1.0 and 2.0 firmware have been tested. Regards, Stanley

Hi, Unfortunately, as mentioned by Stanley the Radar Processor SDK demo is not validated with AWR2243. There are some patches available in this forum provided by some forum members but they are not validated by TI We would have to open this question to the forum community for further support thank you Cesar

Hi Khai, If you refer mmWave DFP 2.2.3.1 example, where same code works for both AWR2243 ES1.0 and ES1.1 based on HW version. You need to implement similar logic in your application C:\ti\mmwave_dfp_02_02_03_01\ti\example\mmWaveLink_SingleChip_Example\mmw_example.c retVal = rlDeviceGetMssVersion(deviceMap, &mssFwVer); /* For AWR2243 ES1.0 MSS ROM FW version '2.2.0.3' and ES1.1: '2.2.1.7' */ if ((mssFwVer.fwBuild == 1) && (mssFwVer.fwDebug == 7)) { gMmwaveSensorEs1_1 = AWR2243_ES1_1; } else { gMmwaveSensorEs1_1 = AWR2243_ES1_0; } Similar way you can check first the AWR1243 MSS ROM version which will have some definite value for ES1.0/2.0/3.0 Silicon samples and based on that select the matching FW version to download. Regards, Jitendra

Hi Jiten, So is there a ES3.0 AWR2243 FW you can send us? In the HW detection, what parameters constitute to AWR2243 ES3.0 device? Thanks, --Khai

There is no AWR2243ES 3.0, only ES 1.0 and ES 1.1 There was an AWR1243 ES3.0 Thank you Cesar

Hi Jiten, Thanks for the clarification. So we have 2 FWs built into the AppImage in TDA2. One for 1243 and one for 2243 since we have both Cascade RF board in 1243 and 2243. My questions are: 1. What is the logic to detect AWR models (1243 or 2243)? 2. If it's 1243, would the same 1243 FW be compatible with all ESx version? 3. If it's 2243, would the same 2243 FW be compatible with all ES1.0 or 1.1 version? Thanks, --Khai

The FW release are usually not compatible. The DFP release notes mention the ES supported. Thank you Cesar
