Hi Sir,
In this project, we design w/ nRF51802-QFAA (Flash: 256KB, RAM: 16KB) and developed the application and bootloader through the nRF51-DK (pca10028).
We can test and upgrade the application through the DFU in nRF51-DK board.
Due to the RAM size is difference w/ nRF51822, I follow the this link and this link to modify the iRAM setting.
The setting is as below.
IRAM1 Start: 0x200025E0 Size: 0x1A20
After modified the IRAM setting w/ above and upgrade the bootloader file to nRF51802 (program w/ nRFGo studio or nrfjprog), the bootloader didn't work.
I can not see the device name"DFUTarg". (Program SD + bootloader)
For support the DFU of 51802, any additional setting need to do?
Thank you.
BRs, Han
