Hi NXP Support,

I am working on building a secondary bootloader for the LPC54102 Sensor processing board. I am using LPCXpresso IDE v7.7.2. So far I built a SBL that can boot and pass control to the user application. I tried with two user applications blinky and sensorhub. Removed the board project from both so that the chip can be used on a custom board. Both applications work well independently without the SBL.

When I load the sensor user applicaiton on top of the SBL it works as expected. However when I try to load the blinky it doesn't work.

I made the same changes on both the user applications. The cr_startup_lpc5410x.c has been modified as specified in AN11610 LPC5410x I2C SPI bootloader and also the flash start location have been modified.

Please find attached image of SBL main.c code

Regards,
OldisGold

I has also solved the issue however luckily best college term paper has helped me with that issue. They has built bootloader for  LPC54102 sensor and as well as sbl in order to control application. Both application has required the same changes.

Okay,

I solved the issue myself.  I just made sure that both applications had the same configurations. The sysinit.c file was probably looking for board.h. Once I removed all references for board.h same on both the blinky and sensorhub applications they worked just fine.
