Which of of two "Low Region" binaries should I use to program FLASH over SPI

The one that says "for PTCx" based patching or just Low Region.

I see their size is about 2K different. What is the difference between these two?

Hello,

Please use the full flash image for a SPI Flash. The low region is for a flash-less system.

Thanks,

Emma

Oh I'm sorry, I meant over I2C not over SPI in my question :-)

The SLVAE21A "TPS65987 and TPS65988 SPI Flash Firmware Update Over I2C" says:

/*
* Execute FLwd with PATCH_BUNDLE_SIZE bytes of patch-data * in each iteration
*/
retVal = ExecCmd(FLwd, PATCH_BUNDLE_SIZE,\
(int8_t *)&tps6598x_lowregion_array[idx * PATCH_BUNDLE_SIZE],
                 TASK_RET_CODE_LEN, &outdata[0]);
RETURN_ON_ERROR(retVal);

Which low region binary the tps6598x_lowregion_array corresponds to?

Hello,

Please use the full flash image the first time the platform is powered up. Please use the Low Region (not the PTCx one) for subsequent updates.

Thanks,

Emma
