I have issue to program nrf52832 with nrfjprog command line.
my program use nrf52formesh sdk.
I developed with Segger Embedded Studio with GCC on the Linux PC.
I modified my_nrf52832.ld file to use UICR and GPIO function on the NFC antenna pins
my_nrf52832.ld file----------------------------------------
MEMORY
{
. . . .
UICR (r) : ORIGIN = 0x10001080, LENGTH = 0x4
UICR_NFCPINS(r) : ORIGIN = 0x1000120C, LENGTH = 0x04
}
SECTIONS
{
. . . .
.uicr_customer :
{
KEEP(*(.uicr_customer))
} > UICR
/* Write the bootloader address in UICR. */
.uicrNfcPinsAddress :
{
KEEP(*(.uicrNfcPinsAddress))
} > UICR_NFCPINS
}
my_code.c file--------------------------------------------
volatile uint32_t uicr_data __attribute__ ((section(".uicr_customer"))) = (0x000000FFUL & (uint32_t)(0x53));
const uint32_t UICR_ADDR_0x20C __attribute__ ((section(".uicrNfcPinsAddress"))) __attribute__((used));
------------------------------------------------------------
With the Segger Embedded Studio, compile, build, flash and run without issue.
Now, I'd like to flash the hex file with nrfjprog command as below
$> nrfjprog -f nrf52 --eraseall
$> nrfjprog -f nrf52 --program my_build.hex
I also able to read/write the UICR as below..
nrfjprog -f nrf51 --memwr 0x10001088 --val oxo2
nrfjprog -f nrf52 --memrd 0x10001088 -n 2
After flash the hex files using "nrfjprog" command, my code not able to access the UICR value.
- again, if I downlod hex files using the Segger studio, no problem to access the UICR value.
Could you help me how can I program using nrfjprog command in this case?
