OTP -Writer AM243X_ALV - SKD 08.04.00.17

Karen Agüero Meza

Hi,

we ported the OTP sample to am243x ALV platform using the sdk 08.04.00.17 , but it doesn't work.

A Code Error ist not displayed, the generated file tiboot3.bin is sent using the USB Interface, the transmision is successfull but the application ist not running. I mean, the customer Key does'nt change.

Only one things :

the VPP pin always is enable at the time the board is powered on, is this correct? or do we have disable it after the transmission?

I try to debugging the sample, it still in the function Sciclient_loadFirmware() in this while

while ((CSL_REG32_RD(Sciclient_secProxyThreadStatusReg(rxThread)) &
CSL_SEC_PROXY_RT_THREAD_STATUS_CUR_CNT_MASK) == 0U) {;}
/* Check the message type and flag of the response */
if (pLocalRespHdr->type ==
TISCI_MSG_BOOT_NOTIFICATION)
{
status = SystemP_SUCCESS;
}

Thanks a lot.

Best Regards

Karen

Hi Karen Agüero Meza,

Are your changes similar to these changes ?

https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/908/keywriter_5F00_changes_5F00_am243x_5F00_evm.patch

If yes, then it should've worked for you. By the way, what is the boot mode you are trying ? How are you loading the tiboot3.bin after loading the SBL ?

More details would be appreciated.

Best Regards,
Aakash

Hi Aakash,

Thanks for the patch file, the changes are ok so far.

The device has a qspi-sbl and it is in UART mode, we load the tiboot3.bin using the recommended Tera Term from https://ttssh2.osdn.jp/index.html.en.

what do you mean after loading the sbl? == > which sbl must be loaded null sbl, uart_sbl, qspi_sbl or the generated sbl_keywriter_am243x.

Maybe we could do a debugging session.

Thanks,

Best Regards,

Karen

Hi Karen Agüero Meza,

The tiboot3.bin already has SYSFW as well as SBL available in the binary and you need not load any SBL prior to loading this binary. Simply send the tiboot3.bin via XMODEM (tera term) post reset if the device is in UART Boot Mode.

Hope it helps.
