Hi Jocelyn, SRAM3 application run it is working out now. I did a small change in unsecure_sram3() definition as below
static void unsecure_sram3(uint32_t start, uint32_t end)
{
MPCBB_ConfigTypeDef MPCBB_desc;
uint32_t regwrite = 0xffffffff;
uint32_t index;
uint32_t block_start = (start - _SRAM3_BASE_NS) / GTZC_MPCBB_BLOCK_SIZE;
uint32_t block_end = block_start + ((end - start) + 1) / GTZC_MPCBB_BLOCK_SIZE;
if (start & 0xff)
/* Check alignment to avoid further problem */
/* FIX ME */
while (1);
if (HAL_GTZC_MPCBB_GetConfigMem(_SRAM3_BASE_NS, &MPCBB_desc) != HAL_OK)
{
/* FIX ME */
Error_Handler();
}
for (index = 0; index < SRAM3_SIZE / GTZC_MPCBB_BLOCK_SIZE; index++)
{
/* clean register on index aligned */
if (!(index & 0x1f))
{
regwrite = 0xffffffff;
}
if ((index >= block_start) && (index < block_end))
{
regwrite = regwrite & ~(1 << (index & 0x1f));
}
/* write register when 32 sub block are set */
if ((index & 0x1f) == 0x1f)
{
MPCBB_desc.AttributeConfig.MPCBB_SecConfig_array[index >> 5] = regwrite;
}
}
if (HAL_GTZC_MPCBB_ConfigMem(_SRAM3_BASE_NS, &MPCBB_desc) != HAL_OK)
/* FIX ME */
{
Error_Handler();
}
}
For the sake of completeness of the ticket, I did two more changes in STM32U585AIIX_FLASH.ld as below,
.testprotection NS_DATA_START : to be replaced with .testprotection NS_DATA_START_2:
and
.data (NS_DATA_START+NS_NO_INIT_DATA_SIZE) : AT (__etext) to be replaced with .data (NS_DATA_START_2+NS_NO_INIT_DATA_SIZE) : AT (__etext)
But please cross check at your end why debugging is not working since past some time, even with untouch ST release package.
I really appreciate your kind support to us. Thank you so much once again.
