Dear NXP,
I am debugging the PN7150 project, and now I have encountered a problem. I read the data twice according to the SDK code, and the correct Answer[3] will not be read when reading the data. If you change it to a fixed length read, you can read it, and you can see what's causing it.
1. Data is read twice, and the first byte of the second data will be lost. Direct one-time read 258 can be read normally, but it takes too much time to verify, affecting the data reading process, and IRQ cannot be lowered, as shown below:
The real number is 40 01 19 00 03 1E 03....
The actual data read is as follows: 0x00 of Answer[3] is missing. 40 01 19 03 1E 03....
