Hello,
We need to pre-program Sflash before programming the application to PSoC6.
If we need to write 64 bytes of hex value such as "cdaa5e5bbc31ed47b9e1f5b07b919815c2e1dde780d9b4701c01f812cad407ef"
Is there any command can write hex value into entire Sflash row?
I have studied "Cypress Programmer 2.1 OpenOCD" but there's only write 4 bytes at one time
./openocd.exe -s ../scripts -f ../scripts/interface/kitprog3.cfg -f ../scripts/target/psoc6.cfg -c "init; reset init; flash fillw 0x16000800 0xcdaa5e5b 4; shutdown"
If I write next 4 bytes into next offset 0x16000900:
./openocd.exe -s ../scripts -f ../scripts/interface/kitprog3.cfg -f ../scripts/target/psoc6.cfg -c "init; reset init; flash fillw 0x16000800 0xcdaa5e5b 4; shutdown"
The previous value would be earsed.
Below is the way I used to read value form Sflash in my application:
uint8_t otp_key1[4] = {0};
uint8_t otp_key2[4] = {0};
emcpy(otp_key1, (const void *)0x16000800, 4);
memcpy(otp_key2, (const void *)0x16000900, 4);
Please correct me and help if my way is suitable.
Thanks.
BR,
Wayne

flash rmw <address> <data> ocd command can be used to program multi-bytes data into dedicate address of FALSH/SFALSH region.
