Hi,
I am trying to create a OTA update for S5D9 IOT Enabler Board(SSP 1.3.2). Initially writing firmware to QSPI (0x60000000) location using QSPI driver . i have verified location using memory browser also I can read value using following function. After rebooting i am trying to read Same location(0x60000000) from boot loader using the following function unfortunately Getting value as 0. What will be the problem ?
Read function
void qspi_flash_read(ULONG addr, UCHAR *buf, ULONG length)
{ memcpy(buf, (ULONG*)addr, length);
}
Bootloader Memory mapping
MEMORY
{
FLASH (rx) : ORIGIN = 0x00000000, LENGTH = 0x0200000 /* 2M */
RAM (rwx) : ORIGIN = 0x1FFE0000, LENGTH = 0x00A0000 /* 640K */
DATA_FLASH (rx) : ORIGIN = 0x40100000, LENGTH = 0x0010000 /* 64K */
QSPI_FLASH (rx) : ORIGIN = 0x60000000, LENGTH = 0x4000000 /* 64M, Change in QSPI section below also */
SDRAM (rwx) : ORIGIN = 0x90000000, LENGTH = 0x2000000 /* 32M */
}
