Other Parts Discussed in Thread: UNIFLASH
Hello,
We have a AWR1243BOOST (IC hardware is version 2.0) board connected to our host processor over SPI.
We have issues with board initialization.
If I foramat the flash with Uniflash tool (flash is empty), board SOP set to 4. Boards boot up correctly and I get the interrupt signal. When I read the Async messaged I get the expected MSSPOWERUPDONE reply message.
(Received raw data: ba dc cd ab 36 a0 22 00 0c 00 00 00 01 00 9a 5f 00 50 14 00 00 00 00 00 ff 7c 0c 00 00 00 00 00 00 00 00 00 02 80).
The POWERUP_TIME is reported around 3ms, which look OK. But the MSS_POWERUP_ BIST_STATUS_ FLAGS is set to 0. Is this OK (Sflash is empty) ?
If it try to powerup the RF part with AWR_DEV_RFPOWERUP_MSG, AWR_DEV_RFPOWERUP_SB ("raw data": 34 12 21 43 05 80 12 00 00 00 00 00 01 00 e7 7f 00 40 04 00 67 8b), I get the expected ACK ("Raw data": ba dc cd ab 16 80 0e 00 0c 00 00 00 00 00 cf 7f 6c 90) but the Async message never comes (interrupt signals doesn't go high). This is because Sflash is empty, right ?
Now if I load Sflash on to the BOOST board (SOP is set to 5), with UNIflash tool using files in \mmwave_dfp_01_00_00_01\firmware\ (files: xwr12xx_xwr14xx_radarss.bin, xwr12xx_masterss.bin & xwr12xx_memswap.bin ).
The board boot correctly I get the interrupt signal, but the MSSPOWERUPDONE look strange (Raw data: ba dc cd ab 36 a0 26 00 0c 00 00 00 01 00 96 5f 00 50 18 00 10 aa 05 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 63 d6).
First of all it is 4 bytes too long, the POWERUP_TIME is reported as 0 and the MSS_POWERUP_ BIST_STATUS_ FLAGS looks strange (0x5aa10).
But this time if i send AWR_DEV_RFPOWERUP_SB, I get the ACK the interrupt goes high but the response is subblock is missing, I only get the header. (raw data: ba dc cd ab 16 80 0e 00 0c 00 00 00 00 00 cf 7f 6c 90)
Question: Could this be a hardware problem or are we doing something wrong ?
We are using our own implementation of your SPI communication protocol. We thing our implementation is correct as we are able to read Async messages and get proper response from AWR_MSSVERSION_GET_SB.
