LPC4088 QSPI Flash write prerformance
Hello,
The write performance to the LPC4088's internal Flash seems slow. Using a single threaded TFTP Server I wrote for mbed, I ported it to the LPC4088. The read (GET) performance is 60% better than the LPC1768. However, the LPC4088's write (PUT) performance is 10x slower than its read performance. Using a 5.63MB file, here are the results using a Windows XP client:
TFTP LPC1768 LPC4088
LPC1768 GET >116 Seconds, 48.6Kbps
LPC1768 PUT > 94 Seconds, 60.0Kbps
LPC4088 GET > 56 Seconds, 100.7Kbps
LPC4088 PUT > 545 Seconds, 10.3Kbps
