AM62A7-Q1: Occasional SBL Authentication Failure

Hi Kevin,

There are multiple points of failure in Bootloader_verifyMulticoreImage function. It may be the case the image itself is read incorrectly in the DDR and so the Certificate length might be read incorrectly leading to the failure even before any request to TIFS for image authentication.

Can you ask the customer to check what is the value of Image Length (imageLen) and Certificate Length (certLen) at the time of authentication failure.

Regards,

Prashant

Hi Prashant 

I check the imageLen and certLen,they are valid. 

The error from function of Bootloader_socAuthImage return value is 0xffffffff

Hi Prashant

I debug find the issue location in function of Sciclient_procBootAuthAndStart

I add some debug info following 

int32_t Sciclient_procBootAuthAndStart(
            const struct tisci_msg_proc_auth_boot_req * authBootCfg,
            uint32_t timeout)
{
    int32_t retVal = CSL_PASS;

    struct tisci_msg_proc_auth_boot_resp response = {0};
    DebugP_log("[DM-sciclient] Enter Function of Sciclient_procBootAuthAndStart... \r\n");
    Sciclient_ReqPrm_t reqParam = {0};
    reqParam.messageType    = (uint16_t) TISCI_MSG_PROC_AUTH_BOOT;
    reqParam.flags          = (uint32_t) TISCI_MSG_FLAG_AOP;
    reqParam.pReqPayload    = (const uint8_t *) authBootCfg;
    reqParam.reqPayloadSize = (uint32_t) sizeof (struct tisci_msg_proc_auth_boot_req);
    reqParam.timeout        = (uint32_t) timeout;

    Sciclient_RespPrm_t respParam = {0};
    respParam.flags           = (uint32_t) 0;   /* Populated by the API */
    respParam.pRespPayload    = (uint8_t *) &response;
    respParam.respPayloadSize = (uint32_t) sizeof (response);

    retVal = Sciclient_service(&reqParam, &respParam);
    DebugP_log("[Bootloader:Sciclient_procBootAuthAndStart]  retVal = 0x%x,respParam.flags = 0x%x\r\n",retVal,respParam.flags);

Hi Tom,

Thank you for the detailed debugging.

Before proceeding further, I would like to have some clarifications.

The issue was first reported in the authentication of the sbl_uart_uniflash_stage2 appimage. But, the latest logs show the sbl_emmc_linux_stage1 failing to authenticate probably the MCU appimage. So, are you seeing authentication failure in both cases?

Also, just to confirm the authentication failures are random and not occuring every time?

Additionally, are you working with a custom board or the TI AM62A EVM?

Regards,

Prashant

Hi Prashant

Yes,The issue found in sbl_uart_uniflash_stage1 and sbl_emmc_linux_stage1.

I test the EVM,it not happen this issue.

Do you mean the issue is occuring on your custom board only?

Also, you did not clarify if the authentication failures are random or occuring on each POR? If random, could you tell the percentage of the random failures?

Yes,it happen in custom board. this is random failures。The probability of occurrence is about 50% when the debugging information is not added, and the probability drops to about 10% after the debugging information is added

I debugging,because requuest the sciclient,but is not response the ACK,so it failure。 please refer above debug info

Hi Tom,

Can you please enable and share the TIFS logs as described here

Hi Tom,

The TIFS logs, if enabled, are collected from the memory as described here

https://software-dl.ti.com/tisci/esd/latest/4_trace/trace.html#trace-memory-buffer-location

Also, if you are working with a HSFS device type, please make sure the DEVICE_TYPE is set to GP only as the DEVICE_TYPE=HS is for HSSE devices.

Regards,

Prashant

My device is HSFS and the device type setting to GP also.

When i enable the TIFS log,from the Wakeup UART0 output some TIFS log,please refer

Hi Tom,

Tom XIAO said:

Those are DM logs. The TIFS logs will be separate and collected from the its defined memory buffer.

I would like you to trap the execution in an infinite loop after the authentication failure and collect the TIFS logs.

What collect TIFS log from memory buffer?

Tom XIAO said:

You could use any debugger to collect the logs.

Or you could dump them with the following function

void dump_tifs_logs()
{
    #define TIFS_LOGS_BUFFER_ADDR 0x4405F000
    #define TIFS_LOGS_BUFFER_SIZE 0x1000

    uint8_t* ptr = (uint8_t*)TIFS_LOGS_BUFFER_ADDR;

    DebugP_log("\r\n<<TIFS_LOGS\r\n");

    for(int32_t i = 0; i < TIFS_LOGS_BUFFER_SIZE; i++)
    {
        DebugP_log("%c", *ptr);
        ptr++;
    }

    DebugP_log("\r\nTIFS_LOGS\r\n");
}

Hi Tom,

Thank you for the logs.

On parsing the logs, we have the following

0x0042C120: BasePort: TISCI_MSG_RECEIVED(TISCI Message interrupt handled): Queue ID: 2 Message ID: c120
0x00820024: BasePort: TISCI_MSG_SENDER_HOST_ID(Message from secure host received): Queue ID: 2 Host ID: 36
0x20C00004: Security: SEC_BOOT(Points of failures during secure boot api call): 0x01 => Certificate length > ASN1P_IMAX, 0x02 => Issue fetching certificate, 0x3 => Issue with Hash operation, 0x4 => Hash comparison fails: 0

It looks like the cause of failure is the Hash Comparison probably due to the corrupted image.

I would think this is mostly a DDR issue. The image is first read into DDR before requesting authentication. So, in case your DDR configurations are not stable then this may cause the image being read incorrectly at times resulting in the authentication failure. Even a single byte corruption in enough for this failure.

So, the question is have you done any stress testing of your DDR?

Regards,

Prashant

Hi Tom,

Let's focus on the DDR part. Before diving into stress testing the DDR, could you please try out the following.

Assuming authentication of `sbl_uart_uniflash_stage2`, apply the following patch, which modifies stage1 linker.cmd, to store the read image at a different location than the load address after the authentication.

diff --git a/examples/drivers/boot/sbl_uart_uniflash_multistage/sbl_uart_uniflash_stage1/am62ax-sk/r5fss0-0_nortos/ti-arm-clang/linker.cmd b/examples/drivers/boot/sbl_uart_uniflash_multistage/sbl_uart_uniflash_stage1/am62ax-sk/r5fss0-0_nortos/ti-arm-clang/linker.cmd

     HSM_RAM_VECS: ORIGIN = 0x43C00000 , LENGTH = 0x100
     HSM_RAM  : ORIGIN = 0x43C00100 , LENGTH = 0x3c800 - 0x100

+    DDR      : ORIGIN = 0x88000000 , LENGTH = 0x800000
 }

This should read the image as it is at 0x88000000 and then request for authentication. If the authentication is successful, the final image is then loaded at the different address 0x84000000.

So, the idea here is when the authentication failure happens, save the read image at 0x88000000 probably using debugger and compare it against the golden image available in PC. If they differs, it will confirm the DDR is the issue here otherwise we will have to look elsewhere.

Regards,

Prashant

Just in case, there are other ways to confirm if the image is read correctly.

You could integrate a simple software based CRC32 computation in the application. Then, just before the authentication request, compute the CRC32 checksum of the image read in DDR. In the case of authentication failure, compare the computed CRC32 with the CRC32 of the golden image.

We don't have code for CRC32 but you should be able to find it on internet. If found, I would think this approach is better than the previous one.

When use the uart uniflash programs,the xds110 not connect the board,so not have the tools can be dump the ddr data .

Tom XIAO said:

I could not understand. Do you not have any external or on-board debugger for your board? If you do, you could connect to the core after the failure and read the data from DDR.

This program is based on the serial port flashing program and the flashing program is running on the DM-R5F core, because the chip is a FS_HS chip, each boot needs to wait for the SYSFW firmware, so when developing SBL, you can't use the XDS110 debugger, not that there is no debugging interface on the board.

So not dump the raw data via XDS110

That is not correct. You could connect to DM-R5F core anytime in the boot flow.

What I would like you to do is trap the execution in an infinite loop as soon as the authentication failure happens. Then, use the debugger to connect to the DM-R5F core and dump the image from DDR.

Hi Prashant

I use the checksum to check the From uart data and after verify data,The checksum calculated twice is really not the same. 

Then i use the debug log trace the uart data and after verify data,somethingmagical happend. When there is an error and when there is no error, the two data are different

the no error log following :

Why happen this case?? and in the SYSFW has been modifiey the DDR data ?

HI 

I check whole DDR from 0x8400000 to 0x8480000,the debug code following 

 {
    uint8_t errststus = 0x00;
    uint8_t sum = 0x00;
    uint8_t *data = (uint8_t*)certLoadAddr;
    for(int32_t i = 0; i < 0x800000; i++)
    // for(int32_t i = 0; i < 0x19d8; i++)
    {
        sum = sum + *data;
        if((*data != gUniflashFileBuf[i]) && (*data != gUniflashFileBuf_bk[i]))
        {
            errststus = 0x03;
        }
        else if(*data != gUniflashFileBuf[i]) 
        {
            errststus = 0x01;
        }
        else if(*data != gUniflashFileBuf_bk[i]) 
        {
            errststus = 0x02;
        }
        else
        {
            errststus = 0x00;
        }
        if(errststus!= 0x00)
        {
            DebugP_log("errcode = 0x%x,index = %d,data = 0x%x,gUniflashFileBuf = 0x%x,gUniflashFileBuf_bk = 0x%x ...\r\n",errststus, i, *data, gUniflashFileBuf[i], gUniflashFileBuf_bk[i]);
        }
        

        data++;

    }
    
    DebugP_log("[sbl uart uniflash stage1] verify fail : raw data checksum is %d...\r\n",sum);
}

and the debug log following

It can indeed be proved that the DDR data has been tampered with, and the next step is to do a DDR stress test

Hi Tom,

If this is indeed the case, could you please create a separate thread for DDR stress testing so that it could be assigned to the right expert.

Once the DDR stress testing is done, we can come back to this and see if the issue still persists.

Regards,

Prashant

Hi Prashant

We use two board do DDR stress test 2 Dyas,it not have any error.

The test log following

Hi Prashant,

I let customer run the DDR stress test memtester for the entire weekends on both of the 2 problem boards (they only have 2 boards and both have this problem). And the result shows that DDR stress test does not fail.

That is beyond our expectation, and we do not know what will be the next step to try.

Thanks,

Kevin

Hi Tom,

Have you used the exact DDR configurations in the MCU+ SDK as used for DDR stress testing?

Tom XIAO said:

I check whole DDR from 0x8400000 to 0x8480000,the debug code following 

Also, how is the gUniflashFileBuf_bk array getting its values? Maybe if you could share the full bootloader.c source file that will help.

Prashant

The bootloade.c from SDK, which it not modified。

In the MCU+SDK not run the DDR stress testing and is testing for A Core for Linux. 

And in the MCU+SDK not modified any the DDR configuration which use the SDK default configuration

Hi Tom,

Tom XIAO said:

I assume you have custom DDR on your custom board. If so, you would need to have the correct DDR configurations for your DDR and integrate them in the MCU+ SDK.

Did you integrate the correct DDR config in Linux before running stress tests which all passes?

Hi Prashant

We use the DDR same of the EVM. So i think the SDK have DDR configuration and we not modified.

Tom

Hi Tom,

Please allow me a day or two to once again go over the whole responses and see if anything was missed.

Thanks for your patience.

Hi Prashant

Any clues, please

BR

Tom

Hi Tom,

You are currently working with MCU+ SDK v9.1. Could you once try out the most recent released v9.2?
