Occur an abort when erasing and writing TCFLASH of S6J334EJ

[haluc_3799201]

We have a Bootloader SW based on S6J328CLSM which works perfect. Now we try to create a Bootloader by another project which used S6J334EJ based on it .And we are facing some problems about erase and program of TCFALSH as below:

1. It is no problem to erase address 0x01A00000 to 0x01BFFFFF, but when execute the erase sector command sequence at 0x01C00000, it occurs an abort (Program Counter halts at the address 0xFFFF000C);

2.Now we only use first 2M of TCFLASH, after erase successful at 0x01A00000 to 0x01BFFFFF(2M), we start programming at address 0x01A00000 using 32Bit Program command, but occurs a bus error when execute at 0x01A00008,and the bit UCEDINT of FUCEDIR reg is 1, and next it will cuase an abort (Program Counter halts at the address 0xFFFF000C);

Is there something that I am missing? Thank you all in advance.

Hello,

1.

0xFFFF000C indicated that  Prefetch Abort occurred. Please kindly refer to below KBA for further analysis.

KBA:

Troubleshooting Guide for Arm Abort Exceptions in Traveo I MCUs - KBA224420

2. For un-correctable ECC error, please ensure continuous 64bit data was written to concerned address with 32bit write commands as TCFlash use 64-bit ECC.

Please kindly provide more information about the issue to your Cypress contact window (CY FAE/FSE) to do further analysis.
