| − | ==Introduction== |
||
| − | On EFR32xG1x series devices, a bootloader is executed after reset. The bootloader is stored in a separate section in the ''Information'' memory space of the device. The section is called ''Bootloader (BL)'' and located at memory address 0x0FE10000. The size depends on the device. Factory-fresh devices are pre-programmed with a simple bootloader which jumps to the start of the internal flash. However, customers are allowed to exchange the bootloader with a customized one which supports more complex tasks like SPI flash, crypto, etc... Therefore, the J-Link software supports erasing as well as programming of this section. |

| − | ==Problem== |
||
| − | When issueing a chip erase, the bootloader section and therefore the bootloader will be erased as well. As a result, the device will no longer boot as no valid bootloader resides in the bootloader section. |
||
| − | |||
| − | ==Solution== |
||
| − | Below, two different solutions are presented. Apart from this, the J-Link software may be adapted in the future to not erase the bootloader section by default. |
||
| − | #Do not perform a chip erase. Basically a separate is not necessary as the J-Link software always performs an implicit erase prior programming if required. |
||
| − | #Program the bootloader (see '''Files''' below) as part of the application or in a separate step after programming the application |
